I have thought about wxWidgets, and I will definitely check that manual out.
My interest in Qt stems from heavy use of GIS and Fortran in my field of study. As an Environmental Engineering student, I routinely solve simulation and optimization problems which take as their input spatially distributed data which is best managed using a GIS system. Most of the models are provided by government agencies such as the USGS or the EPA and are written in Fortran-77. R has the ability to interface with all of these systems and to format the results into nicely typeset reports- however the integration between all of this could be tighter. One of the best open-source GIS systems, Quantum GIS is written in Qt and provides great cross-platform map visualization as well as access to GRASS and an interesting plug-in system. I'm pondering the possibility of a QGIS plug-in which brings R (and by extension Sweave) into the picture and allows visualization, simulation, optimization, analysis and reporting of results all in one package.
