Answering my own question:
// puts the scripts + styles into admin
add_action('admin_head', 'ggh_add_my_tc_button');
add_action('admin_enqueue_scripts', 'ggh_button_css');
// puts the scripts + styles into front-end
add_action('wp_print_scripts', 'ggh_add_my_tc_button');
add_action('wp_print_styles', 'ggh_button_css');
