Custom "normal" page in module
what you want is hook_menu:
  function pushnotifications_menu() {
    $items['admin/config/services/push_notifications/stats'] = array(
      'page callback' =&gt; 'yourverycustomcallbackforpushnotfiers_abc_view',
    );
    return $items;
  }

  function yourverycustomcallbackforpushnotfiers_abc_view($ghi = 0, $jkl = '') {
    // all your logic here
  }

btw: DO NOT DO THIS!!:
$id = $_GET['id'];
Sse drupal_get_query_parameters() instead, if you really have to fiddle with it directly. Otherwise use $args.
