WordPress How To: Easily make an admin panel for a plugin
I find the Admin panel the most tedious part of plugin development–even the slightest changes to the plugin requires major changes to the Admin panel, and it can be hard to remember every option you have in your plugin. However by following a few simple rules, your next Admin panel will be a breeze. Once you have the basic parts down, new options are just a cut and past away. One thing to note is that his Admin panel uses a few features that are best if repeated inside your plugin itself.
