Add a "Stats Board" to my site

Hi,
I'm just throwing this out there in the hopes that you can help.

My client wants site users to be able to fill out a form... just entering numbers. That form would automatically populate... something.

So it would look like this.
Bob fills out:
Exercise: 2
Nutrition: 5
Stretching: 2

It would automatically post his stats plus the totals on a chart. And it would have Tom's current scores under that (with totals) and Jill's and so on. Like a score sheet.

It would be a monthly thing and then re-set.

I have NO idea how to go about doing this. Is there a plugin that does something like this that you know of?

Thanks so much!
