No, it seems that radio/check boxes want only 
strings in the :choices list. I'm not sure the
spec limits the items to strings - at least Lispworks
CLIM is more inclusive.

Anyhow, there still seems to be a problem in the
with-output-as-gadget setup. I end up in the debugger
with some layout function calling sheet-native-transformation
on the parent of the check-box-pane which is NIL
at this time. Anyone got a clue as who is responsible
for providing a parent for this thing?
