I would recommend using a good book as well, simple to start off with. Then when u get stuck you know what to ask. I took a course in it, but all they do is throw a book at you, anyway. The only way you'll learn is by doing it yourself, I think u learn better if you do it trial and error cos u get to know your subject better and u will get a better understanding of whatever you are trying to learn.
...GOOD LUCK.
