change menu GNOME menu by scripting

["christof mestdag" <fenix4life gmail com>]

Hi,

i'm looking for a solution // tutorial // workaround. In short something to solve my problem.

I would like to make it possible to change the menu ( applications , internet ) after the login, before user can access it as some kind of logon script.
I would like to add 1 menu to it where we can find all software provided by the company ( office,.... ) but that ammount of software depends from user to user so it has to be changed by script.

Any one has an idea how to create menu's,... in your gnome startmenu.
