What if the I don't have a reference button widget from same Widget Tree?

How can I do the following?
I have a form that comes up upon activation of a menuitem using 
create_about_dialog or any such function. Now on click of button on the 
dialog window I -
1. get input from text fields - gtk_entry_get_text - as described by you 
earlier.
2. destroy the dialog window.
3. Now I need to display this information in another window, that is _not_ a 
part of the same widget tree. How do I do this? 

Ideally, I would get a reference(pointer) to that widget and display the text 
there. Is there any way that this can be done.

How can I get that reference? If it's too clumsy then how do I share the data 
otherwise?

Do I put the data in a file and tell the widget to read it from there. Even 
then the I would have to tell the widget to refresh it's view for which I 
would need a reference to it.

Lead me to light.

Thanks & Regards
