Adafruit 2.8" TFT display

Hi Guys,

i bought this TFT display from Adafruit and ran the example sketches which works fine. For my upcoming project i want to make

a pushbutton and turn a led on and off. Now i know there a tons of libraries and demo sketches for this available but which to choose?
how can i figure out if the libraries are compatible with my hardware?

help is much appreciated :-))))
regards

forgot to mention i use now the ILI9341 library
