I need to add some site-wide variables (using radio buttons) from within the Admin Panel. I've looked at http://codex.wordpress.org/Adding_Administration_Menus and http://www.deluxeblogtips.com/2010/04/how-to-create-meta-box-wordpress-post.html and also read up about custom fields.
Using custom fields might be do-able but it would be a bit clunky as they're tied in with individual posts and I'd have to get the user to create a placeholder post before they could add the key-value pairs.
Basically all I want is a menu item on the left. Clicking on it takes me to a page of radio buttons. Clicking the radio buttons sets the variables, which would be used within my theme.
Any takers? :-)
