Operator Interface software

I have started to look at what development environment to use for the operator interface GUI. As this needs to be a fast boot lean system, I think it will run on Linux, and so far I have come up with Qt. I have installed QtCreator on both my Xp and Ubuntu machines, so far so good. I am developing a simple app within Ubuntu first, just to get all of the OI comms working between the GUI and the HexEngine, then I will start to get something a little more sophisticated together, and ultimately ported to the target system, which is yet to be defined!
