I used pack and a knowledge of the C calling interface.  It is hacky, and
not very friendly, but works.  I presume one could write a more friendly
interface that uses the types of the Windows data types, and caches them
to a pack specification.

I found that the real problem is the absence of a good way to simplify
Windows programming using Perl (i.e. a GUI builder).
