Yeah, should be pretty doable.

Yep.

There was something called 'InOutWidget' which has two multi-select
boxes and two buttons '>' and '<' between then and you can move stuff
from one box to the other. I think it was possible to drag-n-drop too.

There is something called 'ReferenceBrowserWidget' that pops a kupu
drawer (if I recall correctly) where you can search for items to use
as reference target.

The list of widgets for a page is computed early on. Each widget has a
property 'helper_js' and 'helper_css' which is a list of paths to the
target js and css respectively. After collecting the whole list of
resources, it's uniquefied so we don't include twice and the
js/css include declarations are inserted inside the 'head' tag.
