We have implemented exactly that kind of dialog in the package
Gtkada.Dialogs and Gtkada.File_Selection. These packages provides two
functions that do not return until the user closes the dialog (either
by clicking on the buttons or simply by closing the window).
If you can use these in your application, do it directly. If these
dialogs are not quite what you want, look at the source and do the
same thing for your dialog. This is one of the strong aspects of
free-software :-)

Read the secret documentation: the GtkAda user's guide as a full
paragraph on that. The short asnwer is: No, you don't need to free
the memory yourself, this is all taken care of.
