Let's see, if I understood you right.

We have an app - maybe gnome-app -- like a report-designer -- or maybe none-gnome-app - that creates a report-template.
This template lives in the RAM in form of a (DOM-)tree and can be written to a file as XML for later processing.
Next we have gda-report: It takes the tree and populates it with data. This step is GNOME-independant. 
In a last step we can
- write this new tree to a file as XML for later printing/viewing (GNOME-independant).
- write this new tree to a file as XML and run this through a customzied Jade, as Derek suggested (GNOME-independant).
- render this tree with gnome-db-report using gnome-print (GNOME-dependant).

Is this right? Or does gda-report more than just populating the tree with data?

What I don't understand:
When a user starts with a report-template, where is she asked for here preferences: select some parameters for the queries,
select font family, font size, paper size, .... ?
