Hello Folks! 
Im happy to announce the first port of Octave-GTK that supports libGlade now. 
 
[Significance]: 
With this you can just write your GTK programs, by just writing simple 
event handlers. The actual GUI itself is created by the libGlade using 
GLADE UI description [.glade] files. Now we can use the same idea to make 
application development faster: RAD. 
 
[Development Flow]: 
Use Glade UI Editor to design the GUI. 
Use libGlade to write event handlers. 
Use Octave to write application logic. 
Write a killer application! ;-) 
 
[Downloads]: 
You can get the package from: 
https://sourceforge.net/project/showfiles.php?group_id=114848&package_id=124396&release_id=307008 
http://sourceforge.net/projects/octave-gtk/ 
 
[Examples]: 
There is a simple calculator application using Octave-libGlade & Octave-Glade, 
along with the source code. 
 
[For Impaitent]: 
Sample code: 
#! /usr/bin/octave -q

disp('Ohms law example with octave-libglade') 
 
function calculate_cb() 
     global xml 
     disp('Hello World') 
     i=glade_xml_get_widget(xml,"current") 
     r=glade_xml_get_widget(xml,"resistance") 
     v=glade_xml_get_widget(xml,"voltage") 
 
     amp=str2num(gtk_entry_get_text(i)) 
     ohm=str2num(gtk_entry_get_text(r)) 
     gtk_entry_set_text(v,num2str(amp*ohm))      
end 
 
function main() 
  global xml 
 
  gtk() 
  glade() 
  gtk_init() 
 
  xml=glade_xml_new("ohms.glade","window1","");   
  win1=glade_xml_get_widget(xml,"window1"); 
  glade_xml_signal_autoconnect(xml); 
  gtk_widget_show_all(win1); 
  gtk_main() 
end 
 
main()

As usual Id like to hear from you the idea's and problems that you may face 
during the installation or, use  of the Octave-GTK/Octave-libGlade packages. 
Thanks again. 
Cheers
