I would start with Java, thats the first one I learned since that is what my Intro to Programming class taught. It was quite easy to learn, first program it taught me was the "Hello World".
For me, it is easier to use an book and learn than using an online tutorial. Your learning might be different. But go to your local bookstore, and check out some Java (or other language) books, and if it makes sense to you, then purchase and try, or if you have a laptop, try it right there.
