Looking For Someone To Write A Quick WordPress Widget

I was wondering if someone could create a wordpress widget for me that would work in various themes? Here is what I am looking for:

A Popular Posts Widget. It’s different than the current popular post widgets out there right now, here is how I would want it:

A WordPress blog user creates categories for their posts, for example:
Chicken
Fish
Salads

And let’s say they write a post on “chicken”, they would naturally give it the category of chicken.

I would like a sidebar widget to list the last 3, 5, or 10 posts from a choice of category’s.

In this case, I would want the last 5 post titles from anything posted in the “chicken” category to show up in the sidebar with a clickable link to view the blog post.

I’d want the widget to allow you to choose whether you want the last 3, 5, or 10 posts and also allow you to select the category to choose from, so there would be a dropdown box that lists the category’s on the blog.

In addition, I’d want to be able to use this widget multiple times so I could show the last 5 posts for example from a few different category’s. I’d have one for “chicken” and another one showing “fish”

Lastly, I’d want to be able to know where to put the CSS so that the sidebar widget look and design can be changed.

Thanks!
