You should begin with something simple, such as HTML, which a lot of people have suggested already. Then move to something like the BASIC programming language or Javascript. And then move in any direction you want from there.

If you decide to continue doing webpages, learn PHP, it's open-source, and just about the most common language used for advanced webpages. Learn Javascript also.

If you decide to do desktop apps or whatever, start with something simple like BASIC, then once you a lot of the basics for creating programs down, move on to something more advanced like Java, or C++.
