Graphical Development
Linux has 3 major toolkits used for developing interfaces. These include QT, GTK, and WxWidgets. For development you may want to build the interface on your desktop PC, and then connect with any specific hardware functionality when it runs on the board. You should also be aware of the versions of GTK, QT, and WX widgets available in the current provided distribution as their APIs can all change significantly between versions.
Development environment available for Windows, Linux, and Mac. The most common utility used is QT Creator which includes the IDE, UI designer, GDB, VCS, a help system, as well as integration with their own build system. See QT's documentation for a complete list of features. QT can connect with our cross compilers. If you are working with Linux you can use the same cross compiler and connect it with qtcreator. QT also offers professional training from their website.

GTK Development is possible on Windows, Linux, and Mac, but will be significantly easier if done from Linux. Typically you would use the [Anjuta IDE] which includes IDE, UI designer (GtkBuilder/glade), GDB, VCS, devhelp, and integration with the autotools as a built system. This is only available for Linux.
Hello world tutorial]. This uses the simplest example as it does not use any interface design and creates all widgets from code.
Micah Carrick's GTK/glade tutorial. This will show you how to use the Glade designer (integrated with Anjuta as well) to create an xml description for your interface, and how to load this in your code.
wxWidgets is a cross platform graphics library that uses the native toolkit of whichever platform it is on. It will draw winforms on Windows, and GTK on Linux. While wxWidgets has many [tools] available for development, [Code::Blocks] seems the most recommended as it includes wxSmith for designing the user interface, as well as including an IDE and GDB support.
