Their was/is a module in the X11 namespace, something like TkPerlConsole that will do the job.
Alternatively it is trivial to re-direct STDOUT (an example can be found in Tk::Stderr) to a text widget. From a text widget you can pass command lines with arguments back to the underlying shell.

Here is an idea where you use IPC::Open3 to run bash, then display the output in a ROText widget. It's not perfect, and needs a binding on the entry, so you don't need to keep pressing the Execute button. :-)
#!/usr/bin/perl
use warnings;
use strict;
use Tk;
use IPC::Open3;
require Tk::ROText;
$|=1;
my $mw = new MainWindow;
my $entry=$mw->Entry(-width => 80)->pack;
$mw->Button(-text => 'Execute',
-command => \&send_to_shell)->pack;
my $textwin =$mw->Scrolled('ROText',
-width => 80,
-bg =>'white',
-height => 24,
)->pack;
$textwin->tagConfigure( 'err', -foreground => 'red' );
my $pid = open3( \*IN, \*OUT, \*ERR, '/bin/bash' ) or warn "$!\n";
$mw->fileevent( \*OUT, readable => \&read_stdout );
$mw->fileevent( \*ERR, readable => \&read_stderr );
MainLoop;
sub read_stdout {
if( sysread( OUT, my $buffer, 1024 ) > 0 ){
$textwin->insert( 'end', $buffer );
$textwin->see('end');
}
}
sub read_stderr {
if( sysread(ERR, my $buffer, 1024 ) > 0 ){
$textwin->insert( 'end', $buffer, 'err' );
$textwin->see('end');
}
}
sub send_to_shell {
my $cmd= $entry->get();
print IN "$cmd\n";
}
