An Anchor does that work for you if the text is not rotated.

Annotation are document content not page content, ConcatCTM won't work.
Annotation rotation is tricky because you have to know where all the
tranformations are and do the same on the annotation itself. The simplest why
is perhaps use a generic tag event in the text in question and keep track of
the transformations. When the tag event is called it provides the unrotated
rectangle of the text, transform it and create the annotation. This probably
needs an example.
