This is probably a really really beginner's question, but I would like to know what's the fastest way to get my site on the web so that people can start using it.

I'm learning everything about programming out of books and at home so I don't have much experience.

-->Before I go to like godaddy.com or such site to get a domain name, is there any free sites that would allow me to upload my site so users can use it? I have html,css,php,mysql,javascipt in my scripts so I don't think many sites allow free uploads with such languages.

-->If I can't find a free site, is there any good places to get a domain name and web hosting that supports most languages at a low price? (doesn't have to be professional hosting because I am still a beginner)

-->If I go to say godaddy.com and get their webhosting and domain name, would I be allowed to run php,mysql,python,java on it? (I looked at some hosting sites and most only allow php/mysql)
