Question

I really want to create a stunning-looking GUI desktop application that looks like, for example:

Answer 1

I'm all for WPF/Silverlight, but it really about the platform that you need to support. The real deal is your own talent, as WPF is a powerful tool, if you ain't got the talent to use it, it will look like improved winforms. (Also check out the Expression Studio from MS - which enhance what you can get out of WPF).
