I'm confused. Given the OP code, just how do you "exit from MainLoop"?? There's no "quit" button or anything else...

I presume that while the Text widget is on the screen, you intend to type something into it, and you just want to see whatever was typed there printed to stdout on exit. Is that it? Then maybe something like this: 

use strict;
use Tk;

my $main = MainWindow->new( -title => "Enter options:" );
my $text = $main->Text()->pack();
$main->Button(-text => "Done/Exit",
              -command => sub { print $text->Contents; exit(0) },
              )->pack();

MainLoop;
