Keep in mind whenever "commercial" is used, they are very specificially
talking about CLOSED-SOURCE. You can make money on your programs and still
use the GPL.
You might also want to see their Windows "non-commercial" license:

This is not a problem. As long as your software is free, you may use Qt for
free. When you close it off, you pay for Qt. Simple!
For a bit more info on this topic, check out the chapter I wrote on KDE/Qt
license issues for the KDE 2.0 Development book. It has a FAQ that I found
answers *most* normal questions:
