well, one way of doing this is the toolbar running on your system and
sending signals (say, via short TCP sessions to the server) to trigger
stuff.

Another is by a web interface. buttons trigger stuff by CGI.

If you have your mind set on a remote poping X app, why is rsh not an
option? in a single commandline (which you then attach to an icon) you
can pop up a remote app.

as a last option, if, say, you don't want the insecurity of rsh and ssh
is a mess (setting up non-interactive login) or whatever other reason,
just have a little script triggered from xinetd or DJB daemontools. the
latter sets a few environment vars with the remote IP and port and all
and passes them to the triggered app, and voila. I don't know if there's
an open source version that does that (maybe xinetd does? I know the
regular inetd doesn't)

good luck.
