Does this move?

meybe.
APNG GUI is nice and easy and stress free... unlike every GIF animator I've ever come in contact with. If it's not OCD about dimensions, it doesn't support transparency. If it's not lack of transparency support it's time consuming to put each frame into place: ie, no drag and drop. If its not time consuming, it randomly adds delays that I didn't tell it to, so I get crap like:

But unless I missed something, Firefox (with APNG addon?) is the only browser that shows them moving... curious as to how many people actually see it move.

You ever try out Jasc Softwares Animation Shop 3? You can get it for free, and its way easier than any other gif animator ive seen (im speaking to you, Microsoft...)
