How to close a window in Perl / Tk?

Question

In my Perl / Tk script, I opened two windows. After a certain button click, I want to close one of them. How can i do this? Here is what I still have:

$main = new MainWindow;
$sidebar = $main->Frame(-relief => "raised", 
                        -borderwidth => 2)
                ->pack (-side=>"left" ,
                        -anchor => "nw", 
                        -fill   => "y");
$Button1 = $sidebar -> Button (-text=>"Open\nNetlist", 
                               -command=>  \&GUI_OPEN_NETLIST) 
                    ->pack(-fill=>"x");
MainLoop;

sub GUI_OPEN_NETLIST
{
    $component_dialog = new MainWindow;
    $Button = $component_dialog -> Button (-text=>"Open\nNetlist", 
                                           -command=>  **close new window**) 
                                ->pack(-fill=>"x"); 
    MainLoop;
}
