About Qt
Qt by Trolltech is a C++ toolkit for cross-platform GUI application development. Qt provides single-source portability across Microsoft Windows, Mac OS X, Linux, all major commercial Unix variants, and embedded Linux. On embedded Linux, the Qt API is available as Qtopia Core.
Qt provides application developers with all the functionality needed to build applications with state-of-the-art graphical user interfaces. Qt is fully object-oriented, easily extensible, and allows true component programming. Read the Whitepaper for a comprehensive technical overview.
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. See our Customer Success Stories for some examples of commercial Qt development.

- Microsoft Windows -- 98, NT 4.0, ME, 2000, and XP
