How to build a simple but nice looking UI with WPF

Hi,

I'm trying to learn WPF by myself. I bought a few books, read a lot on the internet and tried some things out.

What I am trying to do is build, with my limited knowledge, a nice looking and simple program.
Lots of the only tutorials show how to build 1 custom window but they do not combine them.
Basicly I want 1 window, divided in 2. In one half a simple menu or buttons to call all my other windows(?) in the other half.

What is the best (and easiest) way to achieve this? Do i need windows, or pages or custom controls or .. ? I read so many things, and so many things i don't fully understand. It would be nice if someone could jump back down to beginnerlevel and explain the basics. :)

I got basic understanding of c#, WPF(databinding, MVVM)
Thanks!

Best regards,
Yves
