Su/sudo is actually the one and only "professional" approach
under Unix/Linux.

Any other way will eventually end up in reinventing su/sudo, which
is pretty hard (security wise) to be implemented.

For a desktop application you may want to look at kdesu/kdesudo (KDE), 
gksu/gksudo (GNOME), beesu (Red Hat). For a console app: su/sudo.
