This is rather simple, you can either probe the Win32 API for the infor-
mation you want, Microsoft's own Keyboard Layout Creator and Michael
Kaplan's tool do this (presumably using either of them will already give
you what you are looking for in a easy to process form), or you can load
the DLLs call the one function they export and dump the returned struct.
The KBDTABLES structure is described in kbd.h, which is part of the DDK,
and also included in the MKLC. I would estimate a suitable dumper to
take about 200 lines of C code, less if you don't care, say, about what
keys dead keys combine with, or ligatures.
