Yeah, the licensing of Qt is either be open-source (under one of the
Qt-exception licenses licenses so no exclusivity for the GPL anymore) or
pay for the commercial version. So yes, if you would like to sell it as
closed-source software you will need to buy the commercial version of Qt
and PyQt. In other words: you will have to pay twice. Don't forget that you
can also sell open-source software, so you don't have to pay. ;)
