Nope, you're never too young.

Case in point: I learned HTML when I was 11, Python and some PHP when I was 12, started Visual Basic and built on PHP at 13, and started C++ at 14 (still working on that one... tough language!).
I'd do basic HTML first, if you don't know it already, and then move on to Visual BASIC and PHP. After that, go for Java or C, then C++. The principles you learn early on with easy languages are used in more advanced ones.
