Interesting.  I don't recall being expected to do the GTK dialog.  At any
rate, it should be easier to do other implementations now that we have an
existing implementation.  I would say the hardest part is the interface to
CUPS.  Since CUPS has a semi-object-oriented C API, producing an idiomatic
Qt interface for it is decidedly non-trivial.  Someone familiar with GLib
may find it easier to think in that way, and hence have an easier time with

The next hardest part is making the custom widgets (like the option grid)
and making them look good.  I'm not much of an artist, so I tried to reuse
existing widgets as much as possible, but that didn't look the way Peter
wanted it too.  I still haven't produced a widget that looks right.  The
spec says that the widget toolkit's native grid widget should be used, but
Qt's grid widget is not designed for such use and would look really weird.

Lastly, I ran into a very strange QGraphicsView layout issue that seemed to
occur on every computer except for mine.  Hopefully, there won't be any of
that this year.
