It is possible to do this with XAML. There is a great XAML resource page for such things called xamalot.com. I have taken one button as a reference: http://xamalot.com/asset/0fc669c8-35f8-49c0-bceb-0d07f1d63691 :

The whole thing to draw with XAML is not that easy, but there are tools out there which allow you to draw and export like Microsoft's Expression Design.
