I have, but I'm not one to learn from reading if I'm honest, I've given it a go, and I've also watched youtube videos (but I just can't listen to people like CodingMadeEasy, just a boring tone to their voice, doesn't engage me) I just love to learn by doing, just slapping together the code and figuring out what it does myself, and if I can't THEN I google it.
In this case I can only suggest to open tutorial, skim it, take example code, and play with it. Window/Graphics tutorials is what you need. I suggest to look at EVENTS and 2D stuff first.
