chmod a perl script to admin richts

How do I chmod a perl program to let it write and confiqure my 
httpd.conf file on my server.
I think the way to do this is to gif this program admin richts so it 
can act as an admin and writte to the system files.
I'm not loged in as admin but as a client on mac osx 10.2.3
I want to mae a program to make it easier to setup my webserver and so 
on, I want to do this from a browser like internet explorrer
