It works like other buffer/window setting (e.g. display margins).

default-wrap-column is the default value for buffers which don't set
wrap-column explicitly.

(default-)wrap-column is only used when creating a _window_ to show
the buffer, as the default for the window's wrap-column (see function
set-window-wrap-column).

So if you set wrap-column, switch buffers twice in the window (to hide
and show buffer).

What do you mean?

It supports variable width fonts -- it is just the wrap-column that
is set in units of the default frame font.

This can be done in lisp - there are packages that does this for
continuation lines already.  Can't remember its name right now.
The relevant function to use is "vertical-motion".
