What about using sudo? you can then use something like this: 

if ($action eq 'Click to Send'){

exec("/path/to/sudo","-u",$user,"/path/to/predetermined/command");

}

This will run the predetermined command as the supplied username. You most defenitly want to use taint here, and probably find a way to do things differently, so that you won't have to mess with the permissions at all.
