Let me save you some time ;).

I had a hard time of finding all the information I needed to create a really usable wpf custom control (user defined templates etc.). Looks like Charles Petzold had to go the same way and was keen enough to write an article for MSDN mag.

So if you want to go the custom control route, read the article at http://msdn.microsoft.com/msdnmag/issues/08/01/Foundations/default.aspx before you start. It's quite easy once you got all the information in place.
