This is a simple example for a Tk based Timeout dialog (timeout: 5 seconds):

#script 

use strict;
use warnings;

use lib qw(.);
use Data::Dumper;

use TimeOutDialog;

my $x;
TimeOutDialog::ask(\$x);

if ( defined ($x) )
{
    print "*$x*";
}
else
{
    print "timeout\n";
}

#dialog module

package TimeOutDialog;

use Tk;

sub ask
{
    my $mw = MainWindow->new();

    my $target = shift;

    my $label  = $mw->Label ( -text => "Please anwer my question:" )->
+pack;

    my $text   = $mw->Entry->pack;

    my $button = $mw->Button
    (
        -text    => 'confirm',
        -command => sub
        {
            $$target = $text->get();
            $mw->destroy;
        },
    )->pack;

    my $id = $mw->after
    (
        5000,
        sub
        {
            $$target = undef;
            $mw->destroy;
        }
    );

    MainLoop;
}
