(Windows XP) Can administrator run any process on guest account?

I try to develop some user control application on Windows XP. the problem is I ,machine's administrator, want this application to run on guest account and guest user cannot end this process by Ctrl-Alt-Del.
Is there any suggestion about running applcation that guest user cannot close it?
Thank you.


Sorry for ask the question without detail.
I'm developing java program for administrator on Windows XP system. This program will start by administrator but it'll stay on guest account for counting time period that guest user use the machine. Then, I need some advise about how to start it and how to prevent guest user to terminate this process.
Any suggestion on XP or java perspective would be appreciated.
