 **Qt** is a widely-known framework for developing cross-platform software that can be run on various software and hardware platforms with little or no change in the code, while having the power and speed of native applications. Though **Qt** was originally written in *C++*, there are its ports to other languages: *[PyQt](../pyqt/)*, *QtRuby*, *PHP-Qt*, etc.
