Hi Monks. I'm a begginer.

I´m using Perl/Tk to make an small aplication... I have one line with two Entry fields and I need store each pair of entry in a hash pair key-value. Until this it's nice but user should can add new lines and for this I need store more hash pairs. How can I store new entries in hash?

My code: 

#usr/bin/perl -w
use Tk;


$mw = MainWindow->new();
$mw->title ("mkFast-A");

$msgi = $mw->Label (-text => 'Making Easy things Easy',
         -relief => 'groove');
$msgi->pack(-side=>'top');

$button = $mw -> Button(-text=> '+', -command =>\&makeline);
    $button->pack(-side=>'bottom', -anchor=>'w');

$but = $mw ->Button(-text=>'hash', -command =>\&print_hash);
    $but->pack(-side => 'bottom', -anchor =>'e');
$but2 =$mw ->Button(-text=>'print', -command =>\&print_seq);
    $but2->pack(-side => 'bottom', -anchor =>'e');

$x = $$a;
$y = $$b;
$hash{$x} = $y;  
print (($x, $y) = each %hash);


MainLoop();

sub makeline{
my $i;
my $j;


my $Seqname = $mw-> Scrolled ('Entry', -scrollbars =>'os');
    $Seqname->pack(-side=> 'left');
    $i = $Seqname->get(); 
my $Sequence = $mw -> Scrolled ('Entry', -scrollbars =>'os');
    $Sequence->pack(-side=>'right');
    $j = $Sequence->get();

$a=\$i;
$b=\$j;

return $a;
return $b;

        
}


sub print_hash{
while (($key, $value) = each %hash){
print "$key => $value\n";
}
}

sub print_seq{
print "$i";
}
