First of all you didn’t mention your OS. In my understanding this lies beneath gtk level. Long time ago I ended up writing device filter drivers to eat all events completely on MS Window 98. It resulted in predictable café customers behavior. In spite of the message box they thought computer is frozen and kept rebooting it. After n-th attempt they talked to administrator. For linux, I guess you have to hack X.

Is there any way to consume keyboard and mouse events in a GTK app? I want to develop an internet cafe app and I must 'block' the computer once the prepaid gets out using a full screen blocking window. The user must no be able to bypass the blocking window using any keyboard shortcut. Any advice on this?
