These days GUI toolkits such as GTK+ or Qt provide convenient methods
for interacting with touch displays including touch, dragging, gestures
(pinch to zoom), multi-touch, etc.
In its simplest form GUIs on touch screens are identical to GUIs with a
mouse. Normal button widgets work great with fingers for example. Even
slider adjusters work pretty much the same with a finger and with the
mouse.
More complicated things like pinch to zoom and multi-touch require a bit
more help from the toolkit.
As Deitmar said, you will have to get a lot more specific in your questions.
