How to add new tabs to admin product page

Hi,

I need to add some new tabs to product page I have the following code that added a tab:

add_filter( 'woocommerce_product_tabs', 'woo_new_product_tab' );
function woo_new_product_tab( $tabs ) {
                // Adds the new tab
                $my_tab = array( 'woo_new_product_tab' =>  array(
                                'title'      => __( 'New Product Tab'),
                                'priority'               => 9,
                                'callback'              => 'woo_new_product_tab_content'
                ));
return array_merge( $my_tab, $tabs );
}
function woo_new_product_tab_content() {

                // The new tab content

                echo '<h2>New Product Tab</h2>';
                echo '<p></p>';
}

What I need now is to add the tab to product admin page, so I will be able add the content for each product in the admin page and not hardcode.
I also need to add more than 1 tab.

I am using woocommerce plugin.
