I am reading the book called:

simons teach yourself C++ in 21 days second edition

I have read first 5 chapter of this book and I am bored with it. It want to learn windows programming in C++ as quickly as possible. I know about some what about

pointers
classes
functions

Am I able to begin programming in windows. I have read a code to create a simple windows app. It uses a lot of windows API calls which I have done some in visual basic.
Please suggest something or some site to learn windows programming.
