I am using wxPython bindings for wxWidgets. Is it possible to create a window in the form in the form of PNG and in the alpha channel count? Take a look at the VS2010 splash screen to see what I mean:

The highlighted areas (rounded corner and shadow) are not sharp; they use the alpha channel to look smooth.
Update : I want not only a custom form, but also a smooth custom form
Update 2 : there seems to be no way to do this with wx :(
