I thought about and may still make a skeleton CGI that could do the list
admin authentication and allow for calling mailman command line scripts.
There is an issue with this however. See below.

See the FAQ at <http://wiki.list.org/x/4030648> and the members.c
program attached to that FAQ. It would be fairly easy to modify
members.c to do what you want except for the authentication requirement.
The issue with the members.c approach is it has no good way to do the
authentication and neither does the calling CGI or PHP script. Thus the
first idea about a skeleton CGI which does authentication and then
whatever you add to it to do such as running sync_members. The
underlying issue is that whatever is doing this must run as a member of
Mailman's group. Thus, members.c is compiled, executable code in a file
with Mailman's group and SETGID. Likewise, All Mailman's CGIs are
invoked by compiled executable wrappers that are in files with Mailman's
group and SETGID.
So the stumbling block here is that members.c can't properly
authenticate the user as a list admin, and the skeleton CGI that I might
create needs a new wrapper. This latter is not difficult if you have a
Mailman source distribution, but if you are reluctant to patch Mailman,
this may be an issue for you.
