Photo gallery widget

Hi there.

Im trying to wrap my head around creating a photo gallery widget.
I can create widgets that work, I can create photo galleries that work. But combined… im stumped ??

Here is how I want the widget settings area to look like:

Title text field
file upload input box
list of uploaded images for that paticular widget.

The parts I cant figure out:
Is it possible to somehow attach the images to each widget instance
Can I use the build in media manager? I tried to put <?php media_upload_form(); ?> in the widget settings, and the upload form looks perfect, but doesnt do anything on submit naturally.

All info, suggestions, ideas and links are most welcome ??

edit: Found a plugin widget that is pretty close to what I want:

But it only works with single images, so now I need help modifying it to use multiple images ?? Gonna ask the author.
