As I mentioned, php/MySQL would be my pick. Easy to learn and use, plus most any hosts provide both for free or included in most hosting packages. Get a php/mysql book(s), there are tons of them out nowdays, many easy ones, even dummies versions, I have a few of those..
Search G for php/msql. I have learned alot here and have gotten quick help many times,
www.sitepointforums.com , they have forums for both php an mysql. There are so many samples on the net, far too many to list.
