i'd like to create an app for my symbian device and like to know what would be the easiest way to achieve this. Im familiar with NET. Framework development in C# and i've also written some apps in python for s60.

What i want to do:
- check if specific app is in foreground or running
- monitor touch gestures (press, swipe left, right, down...)
- start action based on upper results

What would be the easiest programm language to do this? What programm to use? QT Creator, Carbide C++? i'm kind of confused with all this QT, QML, C++ thing...
