wxPack is a full wxWidgets development kit. It comes with wxWidgets source and binaries pre-built with selected compilers (VC10.0 and gcc) so the developer doesn't need to build it. Building wxWidgets is a long and sometimes difficult task and wxPack takes all the work out of using wxWidgets. It has Visual Studio Integration which comes with a 'New Project Wizard' and integrated help. This makes the time needed to develop an application only take as long as writing the code for the application. It also comes with an open-source RAD tool called wxFormBuilder (http://wxformbuilder.org). This cuts the time needed to actually develop the user interface down to a bare minimum. Plus there are also other select contributed widgets included as source and binaries that can be used in a developers application.
