Newbie needs flash CS3 help!

I have a question for whom ever might be able to help me! I’m a total newbie when it comes to flash CS3 and I’m trying to put together a flash website and I need help with coding.
Here’s my problem: I want my site to look like a pop-up book. when you click a button you would see an animation of a house and trees that “pop-up”. I want to set it up so when you click another button, the first animation plays in reverse ( the house and trees fold back into the “book”) before you see a new animation on a new page. I don’t even know where to start! can anyone help me?
