Cross-platform Development Using Qt Creator
Qt Creator [doc.qt.nokia.com] is a complete cross-platform IDE included in the Qt SDK. The IDE enables you to create, build, debug, and run Qt applications across all supported platforms. You can have a single project and deploy that to multiple phones: such as Symbian and the Nokia N9 (using the MeeGo 1.2 Harmattan target).
For more information, please see the Qt documentation [doc.qt.nokia.com]
