Greetings monks! Question for everyone

I'm trying to create a custom frame that can have its border color changed (not just black). I've created a mega widget that basically places a frame inside a frame. I can then change the background of the outer frame to simulate a different colored border. Works great, with one exception; I can't seem to place (pack) objects such as a button on my new cool frame, easily. It want's to pack it onto the outer frame not on the inner frame.

I found that I have to reference the {'inner'} frame directly if I want to pack something onto it. I would really like to be able to just create my new colored frame and place something onto it just like a normal frame.

Any thought?

Here is the code for my mega widget:

package Tk::CoolFrame;

use strict;
use warnings;

use vars qw/$VERSION/;
$VERSION = '1.0';

use base qw(Tk::Frame);
Construct Tk::Widget 'CoolFrame';

sub ClassInit {
    my($class, $mw) = @_;
    $class->SUPER::ClassInit($mw);
}

sub Populate {
    my($self, $args) = @_;
    $self->SUPER::Populate($args);

    my $outer = $self->Frame()->pack(-fill=> 'both', -expand=> 1);
    my $inner = $outer->Frame()->pack(-fill=> 'both', -expand=> 1);

    $self->ConfigSpecs( 
        -background  => [{-background => $inner}, 'background', 'Backg
+round', '#d9d9d9'],    # grey
        -bordercolor => [{-background => $outer}, 'bordercolor', 'Bord
+ercolor', '#000000'],  # black
        -borderwidth => [{-borderwidth => $outer}, 'borderwidth', 'Bor
+derwidth', 1],
        'DEFAULT'    => [$outer],
    );

    $self->{outer} = $outer;
    $self->{inner} = $inner;

}

Program to demo my colored frame:

#!/usr/local/bin/perl -w
use strict;
use warnings;
use Tk;

use CoolFrame;

my $mw = MainWindow->new();
$mw->geometry( );

my $frame = $mw->CoolFrame( 
    -bordercolor => 'red', 
    -background=> 'white',
)->pack(-padx => 5, -pady => 5);

# THIS WORKS
my $button = $frame->{'inner'}->Button(
    -text=> "Exit", 
    -command=> sub{ exit; },
)->pack(-padx => 5, -pady => 5);

# THIS IS WHAT I WOULD LIKE TO DO!
# my $button = $frame->Button(
#     -text=> "Exit", 
#     -command=> sub{ exit; },
# )->pack(-padx => 5, -pady => 5);

MainLoop();
