Simple but useful plugin – Custom Field Panel on Dashboard???

Hi,

I’ve spent most of my day today searching for and reading different hacks and plugins trying to figure out how to do this very simple task for a client of mine.

All I need is this a site wide or globe custom field panel on the dashboard. nothing else just the same custom field inputs that sit on the posts and page edit screens. but on the dashboard.
also I would also like to know how to out put it since it’s not going to be on a single page or post.
the could be example:
<?php $key="mykey"; echo get_globe_meta($globe->ID, $key, true); ?>

I would really love some help with this.
