Well, it''ll take a lot of hacking and probably won''t be very fast. The trick is (I''m a Mac programmer, but I''ve done enough Win32 to see it''l'' work the same way) to render the OpenGL sceen into 2 offscreen buffers, one is the actual image, the other a mask, then you would take custom window drawing code which will create a window in the shape of the mask and copy the image of the cursor into it. As you would be updating the window, rendering 2 OpenGL scenes (although small), copying from the offscreen buffers and moving the window (not necissarily in that order) it would be slow. The other method would be to find where in memory, at the time, the bitmaps and mask for the cursor are being stored and copy from the offscreen buffers into that (this would be faster, but can cause some corruption in memory if not handled well). The second method is by far the best, but both are hard to implement.
