There is a Qt4 GUI development system available for the Pi.
sudo apt-get install qtcreator.
You might want to look here, to set it up.

I don't know if the 'Eclipse' plugin will run on the Pi.
QtCreator can bet set up, in such a way as to allow you to write code (C or C++ or a combination of the two),
compile, debug and run your code from within the Qt GUI running on the Pi.
There are a whole bunch of Qt4 modules available.
Qt5 is available for the Pi, I've never used it, so can't offer any advice.
