In Octave outside of Emacs I run the octave command "plot(1:10)" and it pops 
up a qt window and plots.  Inside Gnu Emacs I run command esc-X run-octave and 
that runs an inferior mode Octave window which calls the same Octave.exe 
program.  Inside that I do "plot(1:10)" and no Qt window pops up.  I have 
tried the Octave command "graphics_toolkit gnuplot;" followed by "plot(1:10)" 
inside the Octave window, and that doesn't help.  This was suggested in the 
following stackoverflow thread for Windows 7 (I am on XP):

So it's a problem!  Eventually I will get frustrated enough to try and build 
Octave and Emacs from scratch and debug it from bottom up, but I'm hoping not 
to have to do that.
