We do all our non embedded coding in Qt.
Project language is English.
Once we get RTEMS running on our hardware depending on time and how much sense it will make we might try to port Qt to RTEMS.
At the moment there is not much to do that I can't do on my own in a relaxed time span.
But as we get nearer to launch (end 2013) we will need quite a bit of work done for the ground station -> Qt Desktop - and then help will be much appreciated.
I'll contact you then again.
