Here's what I whipped up using UNIVERSAL::AUTOLOAD; it seems to actually work! It also attempts to store an already setup UNIVERSAL::AUTOLOAD and use it if the requested package isn't one that should be auto-generated, so it should be safe to use with other UNIVERSAL::AUTOLOAD'ing stuff, as long as this one is use'd last (or the others are smart too). 

#!/usr/bin/perl
use strict;
use warnings;

use lib '.';

use Wx;
use Class::Generate::Auto 'Jouke::Wx' => 'Wx';

my $w = Jouke::Wx::App->new; 

exit;

package Class::Generate::Auto;
use strict;
use warnings;

our $AUTOLOAD;
our %mapping;
my $old_ua = undef;

sub import {
    my $this = shift;
    while(@_) {
        my $prefix = shift;
        my $superclass = shift;
        $mapping{$prefix} = $superclass;
    }
    my $current_ua = UNIVERSAL->can('AUTOLOAD');
    if($current_ua and $current_ua!=\&autoloader) {
        $old_ua = $current_ua;
    }
    *UNIVERSAL::AUTOLOAD=\&autoloader;
}  

sub autoloader {
    my ($package,$method) = $AUTOLOAD =~ /^(.*)::(.*)$/;
    return if $method eq 'DESTROY';
    keys %mapping;
    while(my ($prefix,$superclass) = each %mapping) {
        my ($extra) = $package =~ /^${prefix}::(.*)$/ or next;
        $superclass .= "::$extra" if $extra;
        eval "package $package; use base q{$superclass};";
        die "Unable to auto-generate class $package as subclass from $
+superclass: $@"
            if $@;
        my $method_ref = $package->can($method);
        die "Freshly auto-generated class $package can't $method (prob
+ably $superclass can't either)"
            unless $method_ref;
        goto $method_ref;
    }  
    goto $old_ua if $old_ua;
    die "Class $package can't $method and no autoloader was present be
+fore ".__PACKAGE__." was loaded";
}
