How to trigger $_GET request within admin plugin page?

SOLVED! I find that GET is not working at all! You need to use POST and in the form action you need to type this:

action="<?php admin_url('options-general.php?page=DD_Awesome_Plugin/DD_awesome_plugin.php'); ?>"

Damn! It’s sometimes so hard to do simple task in WP 😉
