Martin:
And besides Bob excelent advice  you still want have a SystemWindow with
fields, buttons, etc you could do:

Your code hier

[done]
                whileFalse: [World doOneCycle].

You should have a method like
 endDialog: aDialog
 aDialog delete.
done _ true.

Triggered by a (SimpleButtonMorph new label: 'END';
             target: self; "hier I suppose you get appropiate code in self
class "
             actionSelector: #endDialog;
arguments: (Array with: aDialog).

See code in FillInTheBlankMorph .

And if you still having trouble, draw exactly how your dialog is , send a
gif or jpg to me and I cook for you !!!

Cheers.
