About Qt
Qt is a cross-platform C++ GUI application framework. It provides
application developers with all the functionality needed to build
state-of-the-art graphical user interfaces. Qt is fully
object-oriented, easily extensible, and allows true component
programming.
Since its commercial introduction in early
1996, Qt has formed the basis of many thousands of successful
applications worldwide. Qt is also the basis of the popular
KDE Linux
desktop environment, a standard component of all major Linux distributions.

- MS/Windows - 95, 98, NT 4.0, ME, and 2000
