Controller Interface

I need to make a kiosk out of a raspbery pie with a 7" touch screen display to control target carriers for a lane at a shooting range. the will need to be buttons at the top of the display (i.e. 10ft, 15ft, 20ft, 30ft, 40ft, 50ft - as well as a HOME button to return to home position. I will need those distances to be easily customizable as every range will be different. I also need a slider to select custom distances - these buttons and sliders will be controlling stepper motors to move targets back and forth in a shooting range.
I will all need the ability to insert a company logo for each unit
