Ok, what I think you are saying is that you want an input widget that you can type in and a msg area to display output, based on what was typed in the input box.
That's actually very simple:
  • create a mainwindow
  • create an entry widget and a msg widget as children of the window and pack them.
  • bind to the enter key in the entry widget a routine that updates the msg area with the appropriate msg.
    That's it. Here's an example: 
    #!/usr/local/bin/perl

use Tk;
use strict;

my $mw = Tk::MainWindow->new();
my $entryv;
my $msgv;
my $entry = $mw->Entry(-textvariable => \$entryv)->pack(-side => 'top'
+,-fill => 'x');
my $msg = $mw->Message(-textvariable => \$msgv)->pack(-side => 'top',-
+fill => 'both');

$entry->bind('<Return>',sub {$msgv = uc($entryv)});
Tk::MainLoop();
