Yes this is very doable, at least it was for my father. Though you are in for some repetitive demonstrations in the beginning...I hope you live close! What really tipped it for him on the learning curve in the beginning was playing a few games (he likes solitaire). This gave him an environment inside the PW that he could learn tap/swipe/pinch without getting lost or changing things accidentally. The only near catastrophe was when he managed to insert the usb plug upside down when trying to charge it (yes this is possible if you are determined!)... my easy fix for this was to color mark the topside of the plug so he could see it.
Hope it goes well for her (and you)!
