Before responding I had tried Stephen's example with a

 (setq inhibit-read-only t)

this alone didn't help.

Is this because there are overlays in effect not (just/only) text-props?

I didn't go any further setting additional buffer variables, but it
may be that a larger set of inhibitions is required (and perhaps
others as well) i.e. temporarily setting:

 (setq inhibit-read-only t
         inhibit-point-motion-hooks t
         inhibit-modification-hooks t)

This sort of approach works works with text-properties (and I have no
idea how it corelates with the widget library)

Would an alternative approach be to forgo the initial widget-insert
and assign text-properties on the buffer contents with the help of
some regexps and only widgetize according to a prop val once the
buffer's setup is finalized?

This prob. moves quite a bit further out from the OP intentions and
may well over complicate  what widgets were intended to simplify :{
