Quickest web framework / tool for an online log of data?

I have a client that is in need of an online log for keeping track of inventory of chemicals.

They need to be able to add chemicals and various attributes to the chemicals, then log when they use a certain amount & be able to log when they add amounts to their inventory.

Then they need reports of current 开发者_运维问答inventory / last X days of activity, and activity of a specific chemical with sorting, etc.

I looked at Google forms with a spreadsheet backend, but it doesn't seem to fit my needs (I want some customization of the form depending on the chemical, be able to easily add / remove chemicals)

The data seems too simple to build from the ground up. Any simple frameworks / product out there I should look at? I'm platform agnostic (.NET / PHP / etc), my priority is that my time as the developer is reduced (I've coded in each platform).

Take a look at Agile Toolkit. It's a PHP UI framework and focused on development simplicity and quick-start.
