Custom button in user Cpanel?

Hello,

I need some help, please, with adding of custom button to the user Cpanel with Image, Title and Description, just like the default onces. It will be linked to the custom page.
From the code I have found there is no html/css code for this purpose - the foreach is used instead:


<?php
foreach($this->buttons as $oneButton){
echo $oneButton;
}
?>


How can I possibly include more buttons?
