To be clear, sudo doesn't care what application you use to edit it.  The
significance of using visudo is that it edits a copy of the file and
verifies the syntax of the file prior to replacing /etc/sudoers with the
new version.  This is significant because, if /etc/sudoers is
syntactically incorrect, sudo refuses to allow ANYONE to sudo.  (This is
not a bug; it's an important security feature.)

I'm not sure why you'd want to add a new group named wheel.  Ubuntu
creates an "admin" group in /etc/sudoers in all installs.
