I know, Anush; but afaik I can just aswell make the website in HTML & CSS while still having the php login script connecting to a SQL database...

What would be the best language to design an entire MMO guild website in? Features would include a (secure) login system through an SQL database; forums; interactive calendar; member roster; etc. I have the most experience with HTML & Javascript but I'm not sure if I can make the entire site in HTML, otherwise I would've certainly gone with that. So can I get some opinions and/or tips?
