That depends rather intimately on how you have set up your code to  
create the windows.

In general, your Button's "clicked" handler can scrape together  
whatever it needs and then call the function that constructs your  
other window.   For example,

   $window1_doit_button->signal_connect (clicked => sub {
           my $arg1 = $window1_arg1_entry->get_text ();
           my $arg2 = $window1_arg2_checkbox->get_active ();

           create_window_2 ($arg1, $arg2);
   });

The main loop is still running, so assuming that create_window_2()  
calls ->show on the new window, everything should Just Work.

There are other issues if window2 is a modal dialog, etc, so, as  
hinted above, more information will get you a better answer.
