If your programs are used in-house and never released, then you don't
have to abide by the terms of the GPL.  BUT (this is a big but) if you
ever release your code or distribute the binary, you must now do so
under the terms of the GPL, because Qt is GPL'd and your use of Qt must
follow those terms.  Another huge caveat is that Qt's proprietary
license says that you can only use the proprietary Qt libraries for
programs that you developed from the beginning with the proprietary
libraries.  In other words, you can't develop a Qt application under the
GPL and link it against the GPL'd Qt libraries and then at a later date
buy Qt and try to relicense your program under something other than the
GPL.  Note that this has nothing to do with the GPL itself, but rather
the terms of the proprietary Qt license (Qt is dual-licensed).
