[plt-scheme] Extension to call Win32 API from MzScheme?

As far as I know, no one has written a plain Win32 library for PLT
Scheme.

But it can done -- the MysterX extension makes many Win32 calls.

The biggest problem you'll face is how to cooperate with the Scheme
runtime system.  In particular, you'll have to make sure your code works
with the GC, and if running under MrEd/DrScheme, it handles Win32 events
without interference.
 
Since I have experience in this area, I'd be glad to provide advice when
needed.
