Qt Showcase Questionnare

Rather than do all this work myself, I thought we could write some of
the answers to Qt on the e-mail list. Please chime in with
suggestions, edits, etc. I hope that even infrequent contributors or
lurkers might speak up.

I placed the questions and draft answers on the wiki:

Cheers,
