Customizable / generic list manager for Admin?

I’ve searched around a bit for the following plug-in but haven’t located a good match. Does anyone know if the following exists, or something similar?

I’d like a plug-in that will create a database table, and supply an interface in Admin to edit the “list” of items saved in that table, and provide simple set of WP functions to retrieve from that table.

The plug-in would provide the WP Admin Dashboard interface to edit the list / table. The Admin interface would be customizable: labelled according to the Settings; the clients who login to Admin can edit the “list” through its own Dashboard module.

So, this would not be a plug-in specific to a standard application (i.e. not an “event scheduler” or a “ad manager”, etc. etc.). Instead, it can be configured through its Settings, so that the Dashboard interface would be labelled to the functionality/context my client needs (i.e. Inventory Manager, Client List, To-Do List, etc. etc.).

I’d need the plug-in to generate the Dashboard back-end and the database, and to provide a basic set of WP functions that retrieve records and the configured field values. It doesn’t need to do any display on the public pages. I would call the plug-in’s WP functions in my own custom templates to display the data.

Ideally the plug-in can support one or more separate lists / tables. Naturally it could get arbitrarily sophisticated, with relationships between lists, but I’m not looking for that much functionality: just a way to provide a skinnable editor of table records within Admin.

Anything similar to this kind of plug-in in the WP world? Do I need to write it myself?
