guile bindings for libwnck?

I'm new to Guile (but not Scheme), and I'm trying to get this program
    http://lilypond.org/~janneke/software/keywise.scm
to run under Debian.

I can't seem to find the wnck module (gnome gw wnck).  There are
libwnck.defs and libwnck-types.defs files, but no .scm files.  Can
someone please advise me how to use the .defs files to create the
necessary bindings?  (Note that the gnome package for Python already
has wnck bindings, in case that gets someone's competitive spirit
fired up :-) Thanks.
