Tutorial for making eye-candy buttons?

Question

I have several apps on my PC with cool custom buttons -  wet-look, shiny, oval. teardrop-shaped, etc.  ( For some reason most of these seem to be media players. ) Where can I find a tutorial that explains how to make eye-candy buttons like that in C# using Windows forms?   

When I Google for "custom buttons" in C# mostly what I get are really basic ones like how to add a background image to a button.   I need a tutorial that goes beyond that.

Thanks in advance!
