Have you looked into "xlsclients"? comes as part of the xaux-clients ipkg
Perhaps that's what you mean by "xlswins". Otherwise writing a small C
app is easy (can post some code if you'd like :) .. but it's basically a
call to XQueryTree(3) ... ).

  Note that tcl/tk can also query this kind of stuff, but it's cumbersome,
and there are issues to do with whether you want to poll the display for
it's windows, or just to be notified when a new windows created ... (but the
former is much more complicated ...).
