Hi.
My son started on Game Maker when he was 8. Check out the book The Game Maker's Apprentice. It comes with a CD for a free version of Game Maker Light. The description on Amazon reads in part: "Game Maker allows games to be created using a simple drag-and-drop interface, so you don�t need to have any prior coding experience. It includes an optional programming language for adding advanced features to your games, when you feel ready to do so." My kid has learned a lot of coding over the past two years. He also used Beginning Programming for Dummies, which uses Liberty Basic.
