I'd suggest VB.NET.
It's easy to learn and can be very powerful. There are plenty of tutorials online (search Google) to get you started, or get a book at your local bookstore/library.
At this point, I wouldn't worry about the question "which is best" since most of the answers aren't going to make sense. If you had a few years experience programming, then maybe more investigation would be needed.
