Making a website

Hi /tech/, what would one have to learn in order to be able to make a website that has a couple hundred pages and a forum. An example: You enter the site for the first time and it detects that so it asks you to complete a questionnaire which then leads you directly to links to specific sections chosen on how you responded. Of course, the user would have the option to not answer and be redirected to the homepage.
So, what should I learn specifically to be able to make something like that and where would I find such information?
The hardware required for maintaining something like that would also be nice to know in regards to pricing and such considering a maximum of 150-200 people simultaneously browsing.
I'm sorry if the questions are stupid or shouldn't be asked here.

Use forum software like phpBB (phpBB is free, vBulletin is probably better but it costs a shitload) for the forum. Use JavaSciprt cookies to detect whether it's the user's first time visiting or not. The forum is in PHP (but you won't have to write it yourself), but the questionnaire could be written easily in JavaScript.

Is that all your website is, a survey that links you to forums based on your results? Or is there more to it?

You can just write your code in a text editor, install Notepad++ or something for syntax coloring. You can install Apache on your computer to test PHP code (if you end up having to write any yourself).

But yeah, when it comes to databases (data stored on a server), PHP and MySQL are your best friends.
