Newfag Needs Help

Okay, tech gurus, I've got a serious newfag issue in terms of learning how to website.

I know what I need to learn for front-end, but in looking at all the shit for back-end programming languages, I'm at a loss; everything states that no one program is "ultimate," because they're all "the best" according to what your needs are.

I need a programming language for a user-generated content website that's going to need a massive storage database for multimedia. Basically, if it would work for deviantart but with perhaps more muscle, that's what I need.

- Must handle thousands of users
- Must handle shittingdickloads of content
- Must have libraries and archives

So, anons, what backend programming language must I master to accomplish this?

Your Daily Double:
Design what you actually want to accomplish first, and well done on paper. You might need more than one server/VPS. 'Might need to THEN read how too accomplish a proper File Management System across multiple servers you spawn around the world on the fly. There's lots of documentation online with multiple implementation. BigTable is the cheating way of doing it.
