I guess I don't understand what you're doing.

Are you using Squeak?

Are you using Morphic?

Are you using the Pluggable* widgets?

Do the query and display things need to be windows?

	Display createWindow

Anyway, I've attached a little example of one window opening another.

Generally you will have a separate model class (or classes), and when model 
aspects change they will send 'self changed: #someAspect' (where #someAspect 
is different for each part of the model).

I am not doing this here just to show you how one window can open another. You 
probably don't want to have windows be their own models unless you don't have 
any more than one window displaying a particular thing at a time.
