I would suggest looking into the Model-View-Controller (MVC) pattern.

I doubt there are many existing tools that would be useful for this,
but like someone else mentioned you could probably re-use and existing
text editor widget for the text view. I don't know of any text
editors that let you reposition the cursor from another process (like
over a local socket or something), but it's possible some exist.
