How to create custom C# widgets?

What is the best approach and/or tool? The trackBar in the MS Visual Studio 2008 Toolbox is inadequate. It needs to be optimized for an 800x480 touch screen in extreme environmental conditions.

I am using C# in MS Visual Studio 2008, but don't know if it is WinForms or WPF (this is my 1st C# project). The target is an old windows-ce tablet.
