xlsclients -l will do it -- it gives you window IDs that you can
pass to import.

If you need to tell several windows apart, you can use programs like
xwininfo or xprop, with -id and the ID you got from xlsclients,
to get more information about the window, like its size and location
on the screen. That should give you enough info to tell them apart.
