Mulsiphix

I have no programming experience. I've been writing HTML for the last decade and worked loosely with web related languages like XML, CSS, PHP, and Javascript. Note that I cannot write anything in any of these. I've successfully modify existing code only and even then such modifications were generally minor.

I want to create a website that will have a member registry that will include names, addresses, personal details, and numerous other fields. Eventually there will be tens of thousands of people within it. I'd like to create a simpler form of MySpace for users to create their own small websites within the community which would include custom backgrounds, wiki's, blogs, and several "user friendly" submission systems for things like news, journal entries, wiki entries, etc... I assume this will require a database and that is something I know nothing about. I've worked with them in the past when I installed and ran phpBB forums but all of the hard work was pretty much taken care of by the installer.

Other than this website I do not plan on "programming" anything. If I can avoid learning multiple languages to accomplish this I would like to. This is definitely a situation where I would like to take the path of least resistance. I'm just not sure what that route is. C# and ASP? Java? CSS and XML? I am willing to put in the time but would like to avoid wasting time wherever possible. What would be the best route to go? Any suggestions would be most appreciated.
