As you all know, im in the progress of making a gta 4/5 clone for SmileBASIC and i need to kniw how to enable touchscreen and make the touchscreen work with a GUI. my question: how to make sprites,how to make a GUI, and how to make touchscreen work with that GUI

Guys sometime after march 28 [probably april 17] the beta or 2nd version of my new and epic game called 'Grand Slash Auto' a gta 4/5 clone. it will be a little bit pixelated but im going to work on getting models from gta 5 pc [the real game] and putting them into my game. it might be a fail and turn into a flat layout 2d gta game but with the help of my trusty friend it should work out great.
