Hmm, we once had a gnuplot GUI online at [0] but it seems that it's being
reconstructed... Don't know if it supported what you asked for.

Anyway, I attached a program that lets you plot different functions on a
panel of your choice. Somewhere in this should be your solution, right?

- in case you want to switch the panel: re-"set terminal ..."
- in case you want to plot another function (or data file): re-"plot ..."

The difficult part IMHO is actually to find out how to redirect the plot to
an X11 handle :-)
