How to set up an Addon similar to the Modifier interface?

[jkcinci]

I've gotten a script that allows me to render and composite my scenes
many times faster than the standard Blender interface.

I wrote a script and it runs very well. I am just trying to get it into an
addon so it will be available to everyone using blender that does not
know how to customize scripts for their scenes.

I need an addon that is similar to the Modifier interface that has the stack.

It needs to have the ability to

1. "ADD" an item to the stack with a dropdown box to
select a certain scene.

2. "ADD" item to the stack with a
dropdown box to select an input node
and a dropdown box to select the input image for that node.

Example Interface Layout at the following address:

If you or any one you know would be able to assist with this project, please let me know, this will be a great benefit to anyone who spends much time rendering or compositing.

Thank you,
your time and consideration are greatly appreciated.
