VPN help

Hi,
I’m trying to create an applescript that would add a VPN connection in the network preferences (CISCO IPsec), and i was wondering if it is possible to create a new service using the system events network preferences suite. I haven’t had much experience with apple script so…any help is appreciated.

Thanks

Model: Macbook Pro (Early 2008)
AppleScript: 2.3
Browser: Safari 531.9
Operating System: Mac OS X (10.6)

Is it not even possible to do it through GUI…? anyone?
