I agree.  Maybe we don't want to take on the task of explaining GUI 
programming from scratch!

While the "Hello World" bit doesn't do much, the bit that will go 
something like:

    package App;
    use base 'Wx::App';
    sub OnInit {
         my( $self ) = shift;
             my $frame = Frame->new();
         $self->SetTopWindow($frame);
         $frame->Show(1);
    }

    package main;
    my $app = App->new();
    $app->MainLoop;

    1;

is quite important, and maybe it's this section we should concentrate on 
here.  Why do we need OnInit?  Can we over-ride MainLoop?

What happens if we drop ->Show()?

What other options go here?

What does Gotchas mean? Is it common problems or misunderstanding or is 
it troubleshooting?
