Thanks - it wasn't really what i searched for but it helped my find the answer - using fileevent:

#!/usr/bin/perl -w
use Tk;

open(CHILD, "perl script.pl|") or die "Nope: $!";

my $mw = new MainWindow;

my $t = $mw->Text(-width => 80, -height => 25, -wrap => 'none');
$t->pack(-expand => 1);
$mw->fileevent(\*CHILD, 'readable', [\&fill_text_widget, $t]);
MainLoop;
        
sub fill_text_widget {

           my($widget) = @_;

           $_ = <H>;
           $widget->insert('end', $_);
           $widget->yview('end');

}

Cool. Didn't know about that one. That seems a little more general in that it looks like it can be tied to a variety of widgets.
