Qt is becoming more pervasive than ever as a cross-platform GUI
development toolkit, especially with the upcoming release of version
4.5.0, which will be licensed under the LGPL on all platforms. I've been
hacking Qt code for nearly 5 years on Linux and Windows, and I love it.
Qt is much more than a GUI toolkit though, it's a complete C++ framework
for developing all kinds of applications, and not just GUIs. It even
includes a Qt API to webkit, so your apps can have a built-in, fully
functional web browser (yes, you can even view YouTube videos in your
own Qt GUIs as of 4.5.0).
During the meeting I would like to create a real program with a
graphical user interface. We could do all kinds of different things from
the classic CD collection manager (becoming increasingly irrelevant) to
an instant messaging client to a disk manager to a web browser (using
webkit). With Qt's new phonon framework, we could even build a video player.
