If you are teaching yourself a language, I think it's most important to gain an understanding of the general concepts of software development. So pick a language (I learned with PHP years ago) and stick with it knowing that you can expand later. Once you have a foundation of the concepts of software development, you can move around and use different languages and you'll pick them up pretty easily because you will then be working mostly with different sytax. I wouldn't worry too much about being locked into the language you learn with but I think PHP or Ruby would be good choices.
