Depends on what you want to create.
If you want to create/program websites, then css, html,
or javascript are your best options.
Like wolfekng mentioned, python is the easiest language
to learn for beginners, because it is a high level language,
the syntax is not confusing.
if your truly interested in programming, you should learn a
object-oriented language like c++ or c#, JAVA, etc...
Object-oriented programming can be a challenge to beginner
programmers to understand, but learning it early will greatly
enhance your ability to create rich applications.
