In my opinion, AS3 (Flash) is a good language to start at and get some idea of coding to create some simple games. Blabob currently uses AS3 to make his awesome games, I guess.
But, if you want a bigger project in the future, you must go towards Java/C++, because they can handle more stuff and have more resources (note that LL: Chapter 3 is going to be on Java because Flash couldn't handle all of that code and Runouw said it would be better to do it with Java).
Also, if you really want something very simple and easy, you can try Game Maker, but I'd choose others because of the freedom.
If you want to start with Flash, then check
this site. It has some simple game tutorials and it is very useful.
