There is essentially no reason to bother with PHP these days. It's a relic and you'd end up having to learn all sorts of arbitrary distracting things.
I can empathise with the intimidation. There was a whole heap of linux administration stuff that I had to pick up to get started. Fortunately, you don't need to do anything like that any more and it can be even easier on windows! You can install the whole stack (ie. Ruby, Rails, apache and mysql) all at once. From there you can just find a tutorial to follow then start copy and pasting stuff from similar applications till you have one that does what you want. (You didn't hear 'develop by cut and paste and google' from me! ;))
RubyStack is one option. The one I have used is InstantRails. I think that one is getting out of date (about a year old) but it probably doesn't make any difference for your purposes.
I don't know what the options are for other web development frameworks. I'm sure there is something simple out there for Python somewhere but I just haven't had reason to look into it.
So if you wanted to get started it is easy enough. Depends on your interest.
How do most people get started with this whole hacker thing?
When I have something I want to do I go do it. Sometimes that means learning stuff like programming. Sometimes it means learning pharmacology. That's probably the underlying spirit behind the 'hacker' mindset.

I rather like PHP. Examples of "arbitrary distracting things"?
tl;dr: Some people on LW have a hard time finding worthwhile employment. Share advice and help them out!
Working sucks. I'd rather not work. But alas, a lot of the time, we have to choose between working and starvation. At the very least I'd like to minimize work. I'd like to work somewhere cheap and comfortable... you know, like on the beach in Thailand, like LW (ab)user Louie did. Then I could spend my spare time on things like self-improvement and ahem 'studying nootropics' all day. I'd like to travel, if possible, and not be chained to an iffy job. It'd be cool to have flexible hours. I've read The 4-Hour Work Week but it seemed kinda difficult and scary and... I just don't wanna do it. I can't code, and I'd rather not learn how to. At least, I'd rather not have my job depend on it. I never graduated from college. Hell, I never got my high school diploma, even. A team of medical experts has confirmed that my sleep cycle is of the Chaotic Evil variety. (For those who read HP:MoR, imagine Harry Potter Syndrome, except on crack. I bet a lot of people have similar sleep cycles.) I'm 18, and therefore automatically low status for employment purposes: I'm obviously much too young to make a good teacher, or store manager, or police officer. I can imagine having health problems, or severe social anxiety, or a nearly useless liberal arts degree, or just a general setback limiting my employment opportunities. And if it turned out that I wanted to work 14 hour days all of a sudden because I really needed the money, well then it'd be cool to have that option as well. Alas, none of this is possible, so I might as well just give up and keep on being stressed and feeling useless... or should I?
I bet a whole bunch of Less Wrongers aren't aware of chances for alternative employment. I myself hear myths of people who work via the internet, or blog for a living, or code an hour a day and still make enough to survive comfortably. Sites like elance and vworker (which looks kinda intimidating) exist, and I bet we could find others. Are there such people on Less Wrong that could tell us their secret? Do others know about how to snag one of these gigs? What sorts of skills are easiest to specialize in that could get returns in virtual work? Are virtual markets hard to break into? Can I just blog for an hour or two a day and afford to live a life of simplistic luxury in Thailand? Pretty much everyone on Less Wrong has exceptional writing ability: are there relatively well-paying writing gigs we could get? Alternatively, are there other non-internet jobs that people can break into that don't require tons of experience or great connections or that dreaded and inscrutable bane of nerds everywhere, 'people skills'? Share your knowledge or do some research and help Less Wrong become more happy, more productive, and more awesome!
Oh, and this is really important: we don't have to reinvent the wheel. As wedrifid demonstrated in the earlier Intelligence Amplification Open Thread, a link to an already existent forum is worth ten thousand words or more.
