I'm sorry, maybe I didn't make my question clear. I'm not really concerned with a "best" programming language. Perhaps just a place to start and where to go from there. I am familiar with HTML / CSS.
i know. again, it depends on your situation. are you familiar with C or a C-based language? or are you totally new to programming? you might find it easiest/quickest to work on PHP. if not, or if you want to learn a currently popular language, you might want to consider ruby or python.
