I have made it a habit to use GLADE for prototyping.  Once I have a
part of the GUI looking about right, I try to organise it in sensible
packages.  Things which seem to be reusable are named as child
packages of GtkAda, while more specific parts are kept in packages
related to the project.

I find it hard to see any arguments for keeping the whole GUI in one
package.  As far as I can see, there is nothing that makes the GUI
part of a program sufficiently different from other parts of a
program, to make it sensible to ignore the general rule of separating
code out in units with well-defined (and minimal) interactions with
the remainder of the program.
