Hello Gautier,

A first step, you can make as the concepteur, is to build the AZip user interface with Glade (the GTK UI builder).
https://glade.gnome.org

That is to create all the necessary panels, widgets and signals.
Then you will get an XML file.

This file can be parse with Gate3 to create an Ada skeleton:
https://sourceforge.net/projects/lorenz/

A modified version is here:

See my French tuto:
http://blady.pagesperso-orange.fr/a_savoir.html#gtkada

I can help you with this step.

Then with the Ada skeleton it will be easier to fill it with your Ada code with help of GTKAda users.

Regards, Pascal.
