if i under stand what you're looking to do:

# saved means that customer is saved and the button is creating new
# if not saved then the button saves the customer
my $saved = 0;
$button->signal_connect( clicked => sub {
        if( $saved )
        {
                create_new_customer(...);
                $button->set_label('Save customer');
                $saved = 0;
        }
        else
        {
                if( $saved = save_customer(...) )
                {
                        $button->set_label('Create new customer');
                }       
        }
});
