Python is a pretty good place to start. It's simple, and a high level language. It isn't really used in the gaming industry much, but it will teach you basic things. Lua is also a good language to start out with, it is kind of like C, and it has had some popularity in the gaming industry. (It was used for Neverwinter Nights, and Escape from Monkey Island.) After the easy stuff, C++ would be a good language to learn.
