It is not Ada specific.

GTK is designed with widgets having no fixed layout in mind. There is a 
complex mechanism how children widgets communicate with the parameters 
in order to obtain their sizes. A GUI builder does not work well in this 
environment. It does not work well even when widgets are fixed, e.g. 
Win32 GDI with MS resource editor. Then GTK is permanently under 
incompatible changes. GLADE is poorly maintained and never catches up 
with the changes. All this makes GLADE programs practically unmaintainable.

Just create widgets and put them into containers (boxes, grids, tables) 
from the program. Always create your specific widgets by deriving from 
existing ones (usually containers) and doing initialization in 
Initialize, which you call from Gtk_New. Use GTK signals and properties. 
You can define new signals and properties for your widgets when necessary.
