Create a transparent window the size of the whole screen, mark it always-on-top, calculate the regions of your other application windows, and make the non-window regions of the top window grey.

I suppose you could just position your own application windows on top of the transparent grey one, with it being above all the other ones, but getting a tricky z-order scenario like that right, especially in conjunction with other apps that might also be doing z-order tricks, is tough.
