Break it down
Right,

Not a simple task, if you want to do it properly, you will need to do the following:

Install a web server (apache, IIS or similar)
Install (and configure) database software (MySQL, SQlite or similar)
Install forum software (I recommend phpbb)
Write your website (the forum front end will already be there as part of the phpbb install)

Full configuration and fine tuning can be done later but the setup above with basic functionality is just about achievable in a day (depends how comfortable with server software you are).

Let me know if you want more specific pointers.
