Language with Some Decent Game Dev Stuffs?

Like, libraries/namespaces that are already made so that I wouldn't have to make all of my own. >.>

Even if I end up making something less impressive than a Pong game that doesn't work, it's alright with me. I just want a fun way to gain some programming experience in my spare time, and games seem to be it. Just a way to get familiar with thinking abstractly, I guess.

What do I do?

Why not use C++ if I'm new? What else should I use to get started? I'm not COMPLETELY new. I understand the idea of calling methods and using objects to do stuff. Isn't that all I really need to know to get into any language? Just the syntax, some general concepts and then I'm off to find a way to practice until I'm comfortable with several languages?
