I'm afraid my connectivity for the next few days is poor enough
that I don't have the resources to do that.  I suggest google with:

  site:lists.gnucash.org

Okay.

Scheme is super simple to learn, which is why it's been used as
an intro CS language for decades.  Anyone can pick up the syntax
quickly.  Granted, mastering all the skills can take a bit more
time, but that's what online references are for.  I like the 
"MIT Scheme Manual".

You can take an existing report that's "close" and then modify it
as you see fit.  See the wiki page on Custom Reports.

I presume you've played with the report options of the various
reports to verify that what you want isn't available?

Yes, there is a report API.  It's the C API translated into Scheme.
You can see the C API via the Doxygen build.  Unfortunately the
documentation isn't complete.
