Building PHP Admin Backend for pretty simple site

I have taken over a website that is about 5 years old and the backend is pretty bad and a bit broken.

I would like to build a new backend "Quickly". I have PHP 5.3.4 and a mysql database.

There are 5 or so tables.

• Categories (eg, headphones, turntables)
• Products (they have a Category Foreign Key, eg to say what category this product belongs in).
• Products also an image field (path to im开发者_如何学Cage file), so image upload would be good.
• All the other tables a flat.

I would prefer not to hand code this system, I looked at building the backend in Symfony, that looks pretty awesome but looks like few days work.

Any suggestions other than PHP MyAdmin (please no...) to allow my client to admin is backend?

Thanks, John.

Caveats: most "application generation" software has a clichéd title and is aimed at novices.

• ScriptArtist - highly customisable
• SQLMaestro - nice interface
• AppGini - feels clunky
• PHPMyEdit - Open Source, feels dated
