Have the non-GUI code return the message and have the GUI code act on it. 
# I changed the last line in this Auto::GUI sub
sub fire_up_front_end{
  my $self = shift;
  # display the gui
  # later... a button will call MakeArticle
  my $mk = Auto::MakeArticle->new;
  $gui->msg($mk->make); # return to the GUI object
}

# And changed this Auto::MakeArticle sub
sub make{
  my $self = shift;
  
  # do stuff to make page
  
  return "message from MakePage";
}
