Except, the 'non-commercial' edition of Qt for Windows is not distributed
under a GPL-compatible license (unlike the X11 version of Qt). 

It *sounds* like they want you to be able to develop free (as in free
beer) software; they go so far as to insist that you may 'include an
executable version of your software'. My software won't actually execute
without qt-mt230nc.dll, so I assume it's okay to include it.  
However, I would prefer to not distribute the 'entire package', which I
take to mean as the entire Qt Non-Commercial Edition, which includes,
among other things, Qt-Designer, API documentation, etc.

Of course, I can't find *any* examples of free Windows Qt distributed as
binaries.

Indeed. I was just wondering if anybody in this group has any experience
with these licensing issues...
