I'm starting off as a programmer and want to expand my horizons, what languages should I try to learn?

Ok so I'm what you could call a total newbie at coding, I've only learning html and css (which some don't even count as real coding.) but none the less that's what I've done. I want to get more involved in complex languages and challenge myself, but I'm sure where to start. I'd like to focus on modding or creating things like cleverbot and maybe an app or two. What lanuage should I start off with, and then what should I move onto after I've mastered said language? Appreciate it.
