The Qt toolkit is a C++ class library and a set of tools for building multiplatform
GUI programs using a “write once, compile anywhere” approach. Qt lets
programmers use a single source tree for applications that will run on Windows
95 to XP, Mac OS X, Linux, Solaris, HP-UX, and many other versions of
Unix with X11.A version of Qt is also available for Embedded Linux, with the
same API.
