If you mean: you wrote a CUPS backend that tries to directly display a GUI, that will not work - the backend runs as root in a separate user session and has no access to the desktop.
In general, trying to communicate directly with the job's user from a backend or filter is a bad idea - the user may not be logged onto the system. The usual method of dealing with this is to setup an IPC channel (domain socket, etc.) between a custom backend and a (running) desktop GUI application.
