I doubt I'll get around to writing the DTP app until next year at least,
since I want to do this Pango work and then work on a printable canvas
widget/component and help sort out gnome-print.

I haven't thought about the data structure too much yet. I was thinking
of cannibalizing GtkTextView (as that already does all the PangoLayout
stuff) and using GtkTextBuffer initially, and then using something else
if that isn't scalable. But I'll have a look at your code. I'd be
interested in how it compares to GtkTextBuffer in terms of features,
speed & scalability.
