AFAICT, Qt for Unix/Linux/MacOSX has three licenses available: the GPL,
the QPL, and a proprietary license (which costs).  Qt for Windows is
available under the GPL and a proprietary license.  The QPL requires that
any applications you develop with a QPLed component are source-available
and freely redistributable, but does not require that they be distributed
under the QPL or any other specific license.  It is semi-reciprocal.
