I am seeking for some advice what would be best approach to draw this shape thru GoJs.

Do you mean to connect two Nodes? If so, try Balloon Links.

Also see Comments.

Is there a way to implement it, not as a link, but as two shapes?

  1. the regular rectangle box.
  2. the tail that can be dragged to point at something (not a link) and moved along the sides of the rectangle.

It certainly sounds as if you really want there to be a relationship between the “call-out” object and some other object such as another Node. Normally that would be implemented as a Link.

Implementing support for a completely new kind of relationship is a lot of work and is not easy to do.
