Module development and code questions

I wasn't sure if this should be in support or not. I'm working on a Drupal website that has a main menu.
In the main menu, each item has children links and each child link goes to a page that lists events.

I'm trying to figure out how to dynamically disable the children links for the pages that do not have any events tied to them.

Using t() function I can not translate normal text like "sample text". I have added code t('sample text') & t('sample text', array(), array('langcode' => 'fr')) to page.tpl.php page. But both are not working.
Kindly help.
