None of the GUIs for Octave that had been developed thus far were part of
 +
Octave and there is a reason for it. All of them failed at a very important
 +
point, integration with Octave. They treated Octave as a foreign black box
 +
using pipes for communication. This approach is bound to fail with each new

version. Any fix made to make them work with a new Octave versions would only

be temporary. This included QtOctave (now abandoned and incompatible with
 +
newer versions of Octave), Xoctave (which is proprietary and commercial), and

GUI Octave (which was proprietary and no longer available).
  
The previously existing GUIs were not part of Octave itself.  The integration within Octave was rather bad, as all of them treated Octave as a foreign black box and used pipes for communication.  This approach is bound to fail with each new version of Octave, as any fix would only be temporary.  For historical reasons and to honor the approaches, a short list of previous GUIs for Octave:
