It would be the same with wxWidget (wxWindows is the old name) and gtk+
because both are also C++ libraries. So you need a C wrapper library ( the
libborqt.so ).

You can write a solid executable but then you can only use C libraries
like gtk (without the "+").

Qt is used by KDE and many Linux programs that are not KDE applications.
The big advantage of Qt is that it is platform independent and it is not
only a widget framework for C++. It introduces extended runttime type
information and it contrains a whole classes framework (e.g. QString,
QStringList, QList, QHashList, QLocale, ... [ for more see the Qt
documentation] ).

It is possible to link directly against a C++ shared object with Kylix
(Delphi). But it is not that easy. The gcc 3.x has an ABI (application
binary interface) that could be emulated by a Delphi class. For gcc 2.9x
C++ libraries it is more complicated because the VMT is not equal to
Delphi's (positive entries).
