Have you any idea how to make window transparent using pygame?

That alone won't help. First of all, the alpha only is applied to the 
contents of the pygame window - so you need to capture the background 
behind that first and put it in the window as background. But if that 
background changes, you won't be notified.

But that still won't rid you of the window decorations...
I guess one could do that with OS-specific calls to window-handles or 
the like (and in PyObjc its a no-brainer, as the Mac windowing-system
  supports that natively)

But in pygame, there is no API for that.
