I think you can probably force the current implementation to
work this way, with a little work.  You'd need to *slightly*
change the above spelling though, and make sure you were
using one of the standard Python implementations and not,
say, something that didn't follow the language reference:

class MainFrame(FrameDescription):
     b1 = ButtonDescription(
         size = (40, 40),
         text = "b1",
         )

That's pretty close to what you asked for.  You're welcome,
in advance. <wink>

(Actually, I suspect you wanted slightly different behaviour,
but I'm not clear on what.)
