mobile keypad logic in dm3730 based development board with Linux OS

Hi,

 We need to develop a mobile keypad logic.We connect the keypad to dm3730 through TPS65930 IC which is having a built-in keypad controller, OS used is Linux. In current situation if we press a key button, it display a corresponding character on the terminal. Our aim is to develop a QT application whose  working is same as a mobile keypad(If we press a button first time it display 'a' , quickly press again it display 'b', next times 'c'   and so on). We know "evdev" linux utility will give the event occured time and values of keyboards to the user space. Is it possible to implement the mobile keypad logic in user space? or is it required to  implement  in kernel space ? Also  the application we want to develop in QT. Is it possible to develop the mobile keypad logic in QT using evdev utility?

Thanks and regards
