Hi,

being curious I digged around a bit having more or less no clue about the building blocks of wxPerl, but I got a little nice looking window with the following code: 

use strict;
use warnings;
use Wx;
use Carp qw {cluck};

package MainWindow;
use Wx ':everything';
use parent -norequire, 'Wx::Frame';
sub new {
    my $class = shift;
    my $self = $class->SUPER::new(
        undef,
        -1,
        'Test',
        [-1, -1],
        [-1, -1],
    );
    # we need a panel
    my $panel = Wx::Panel->new($self);
    $panel->SetBackgroundColour(wxGREEN);
    $self->{panel} = $panel;

    # create a list control with content
    my $lc = Wx::ListCtrl->new(
        $panel,
        -1,
        wxDefaultPosition,
        wxDefaultSize,
        wxLC_REPORT,
    );

    $lc->InsertColumn(0, 'Column1', wxLIST_FORMAT_LEFT, 150);
    $lc->InsertColumn(1, 'Column2', wxLIST_FORMAT_LEFT, 150);
    for my $i (1..10) {
        my $id = $lc->InsertStringItem($i, "Item $i");
        $lc->SetItem($id, 1, $i, -1);
        $lc->SetItemData($id,  100 + $i);
    } 
    $self->{list} = $lc;

    # put sizers in
    my $panelsizer = Wx::BoxSizer->new(wxVERTICAL);
    my $mainsizer = Wx::BoxSizer->new(wxVERTICAL);
    $panelsizer->Add($lc, 1, wxEXPAND|wxALL, 0);
    $panel->SetSizer($panelsizer);
    $mainsizer->Add($panel, 1, wxEXPAND|wxALL, 0);
    $self->SetSizer( $mainsizer ); 
    
    return $self;
}

my $app = Wx::SimpleApp->new;
my $win = MainWindow->new;
$win->Show(1);
$app->MainLoop;

Probably it helps you to find out what was wrong initially.
