MultiWii

The old multiwii_conf is written in processing. Easy to install, easy to handle, free. Easy to modify.

How about writing something to be able to enter waypoints / display gps location in realtime etc?
There is a neat package to display maps in processing. Its called "http://unfoldingmaps.org"

In just 15 mins i was able to get it up and running and to put a marker on my field. Seems simple enough



Or, is there something similar already? (no, i dont want to install a compiler)

Edit:
here is a simple "mission planner" test and the 1100m mission for my boat
which runs an extremely simple GPS-only RTH firmware https://github.com/Cesco1/ArduRTH

Hi Plüschi,

Sorry for my late response. Up to Multiwii 2.3 I have used WinGui for that purpose. But, I doubt that the software will be maintained in the future. So, I appreciate your effort. Do I understand you correctly, that you have adapted the ArduRTH software? Is it being hosted somewhere? What items should be worked on in the future? I prefer the processing approach over the Microsoft Visual Studio approach of WinGui and agree to the points you made. It would be interesting to see more views on the waypoint topic and maybe to set up an own project.
