Custom Fields to output a list of links

First of all I love wordpress ! But I am a primate when it comes to php, and I would be deeply appreciative of some help with this problem.

I would like to output data from the custom fields which presents itself as a list. Moreover I’d like to be able to create a link list item with a description.

Can someone help me with the logic of this ? I would like hypothetically to be able to enter links and description into the custom fields, and have a list of named links outputted.

I think a lot of people could make use of such a function. What I have in mind is being able to craft very intentional and specific lists of related content underneath a post.

Thankyou very much

… this is my early code attempt but I think the logic is really confused… one item is outputted but

<?php $values = get_post_custom_values("related");
if ($values[0]!="") {
echo "<H3 class=\"related\">Related Links:</h3>";
echo "<ul class=\"related_list\">";
echo "<li>$values[0]</li>";
echo "</ul>";
}
?>
