QT

Qt is a cross-platform application and UI framework. Using Qt, you can write web-enabled applications once and deploy them across desktop, mobile and embedded operating systems without rewriting the source code.

Qt was initiated by Nokia but the recent deal between Nokia and Microsoft changes the perspective of Qt.

Qt Creator is a cross-platform IDE (integrated development environment) tailored to the needs of Qt developers.
