Thanks for the idea. Events are the key. I just started a one shot timer to trigger the wizard after the main loop is started. 

use strict;
use warnings;

use Wx;

package WizTest;
use base qw(Wx::App);   # Inherit from Wx::App
use Wx::Event qw(EVT_WIZARD_FINISHED EVT_WIZARD_CANCEL EVT_TIMER);

sub OnInit {
    my $self = shift;

    my $wizard = Wx::Wizard->new( undef, -1, "Wizard test" );

    # first page
    my $page1 = Wx::WizardPageSimple->new( $wizard );
    Wx::TextCtrl->new( $page1, -1, "First page" );

    # second page
    my $page2 = Wx::WizardPageSimple->new( $wizard );
    Wx::TextCtrl->new( $page2, -1, "Second page" );

    Wx::WizardPageSimple::Chain( $page1, $page2 );

    # use a timer to start the wizard after we have the event loop run
+ning.
    my $timer = Wx::Timer->new();
    $timer->Start( 50, 1 );
    EVT_TIMER( $self, $timer, \&StartWizard );
    
    EVT_WIZARD_FINISHED( $self, $wizard, 'WizardFinished' ); 
    EVT_WIZARD_CANCEL( $self, $wizard, 'WizardFinished' ); 

    $self->{wizard} = $wizard;
    $self->{start_page} = $page1;

}

sub StartWizard {
    my $self = shift;

    $self->{wizard}->RunWizard( $self->{start_page} );
}

sub WizardFinished {
    my $self = shift;

    warn "Wizard finished: $self @_\n";
    $self->{wizard}->Destroy;

    return;
}


package  main;

my $app = WizTest->new(); # New HelloWorld application

$app->MainLoop;
warn "Exited main loop";
