Default [Q] Is there a way to lock down settings on Android?

I set up my galaxy and gave it to mom so she can call me overseas using GrooveIP, Skype, and also so I can send pictures etc.

I just learned she somehow deleted the WiFi profile and also lost the saved password on GrooveIP and Skype disappeared from home.

Is there anyway to lock everything so phone is like read only with no way to make any changes?
