Sergio,
A Touchscreen needs hardware to support the detection of where the screen is touched. The hardware will include software drivers that make it work just like a mouse. All of the VFP Mouse based events work fine with the touchscreen.
You'll have to design your controls to be big enough to be touched with a fingertip. You also need to make sure they aren't placed too close together.
