No, gksu _is the right tool to use. sudo should never be used to

Since the above page only says "don't do it!" but doesn't explain what
might happen otherwise: what problems are to be expected if one starts
a graphical application with sudo?

With sudo some applications access / modify the user's config files as
root. From then on they are owned by root and the user can no longer
access / modify them. That leads to unusual error messages which only
long time users can trace back to the permission problem. With gksu (or
kdesu if you use kde) this problem is avoided.
