My Connectors package has this already.
The NCMakerButton is a regular IconicButton, but it holds onto a prototype
Morph. When you press it, it duplicates the prototype and sends it a message
of your choosing.
The NCButtonBar is a container for these. It comes with a menu for adding more
buttons, or you can just drop new ones on the bar.

Not really. In Morphic it's more common to have a parent morph that does the
grouping and arranging. The parent can use a LayoutPolicy to choose how to
lay them out.
Look, for instance, at what happens when you do a selection (making a
SelectionMorph) and tell it "place into a row" from the Selection's halo
A new Morph is constructed and all the morphs in the selection are added as
children of that morph. The parent is set up as a table, with layout from
left to right and no wrapping.
