What have you tried? Using a popular search-engine I found this set of tutorials (first thing it returned) for, what appears to me, your exact dilemma, but if you want to figure it out with a little less guidance, then asking more specific questions and telling us what has and hasn't worked for you is going to help us best help you.
For starting out, and for creating a simple game like Pong, it is best if one doesn't directly go for tutorials.
He should instead spend at least some hours on pen/pencil and paper trying to figure out how his game would work.
I didn't mean to imply that following a tutorial was the best idea. I was just providing options (and suggesting that there are existing answers to a lot of questions).
