Creating MSWord Callout boxes via Automation

(D7, Office XP)
1)  I need to create Callout boxes via Automation in MSWord.  I know how to
open an existing doc but can anyone get me started with the Callout stuff?

2)  I am also trying to Automate MS Publisher.  Seems MS has finally
released a .TLB for this.  Is there a VBA help file too?
