Best way to create interactive GUI apps with octave?

[Miguel Bazdresch]

Hello,

What is the best way to create interactive GUI apps with octave? For
example, I would like to have a window with three sliders controlling
the amplitude, frequency and phase of a cosine that is plotted below
the sliders. The purpose would be to make visually attractive demos
for my students.

So far, I have come up with these options:

* create a C++ application using octave as a library, and a C++ GUI
package such as Qt
* use gtk-server (http://www.gtk-server.org/)
* a couple of old and apparently unmaintained projects I found with
google, such as octave-gtk and octave-fltk

I could also, of course, do this in scipy or scilab, but I would
really like to do this with octave, since this is the language my
students know best.

Does anyone have tips or experience to share? Are there alternatives I
am missing? Will the new FLTK backend work for this purpose? (I have
found precious little information on this new backend).

Cheers,
