i believe it is seen as a memory location. I designed the FPGA layout and used that to build a PetaLinux system. I can succesfully test all the Leds and Pushbutton in the linux terminal using the demo application provided.

Then you should extract the necessary components from the example in order to create a small library that can be used to get the information you want.

I had the exact same idea. It didnt go well the folder of said GPIO-demo app contains a .c file , a make file, and a .bb file . Are those importable into QT.

Qt is a C++ framework, so yes you can use C code.
