new post links to new (sub)page

I have a setup with a navigation of pages and subpages.
I have also set up categories.
I would like to have a post (cat=announcement) on the frontpage that announces that a new subpage has been added with a link to the new subpage (or even the parent page). Sort of a ‘a new subpage has been added. Go check it out’
The equivalent of a latest post but for pages.

Any opinions on how to tackle this ‘as easy as possible’ for an end user?
