Your best bet is to modify the built sources to install your report
along-side the existing installed reports.  You could modify the
installed reports directly, as well, but the other option is a bit
safer.

http://www.google.com/search?q=learning+scheme

http://community.schemewiki.org/?category-texts seems particularly
useful.

The existing reports will demonstrate by example.

http://cvs.gnucash.org/docs/HEAD/ has documentation generated from and
over the C sources, though it's not all exposed via scheme.

Look for the gwrap "*-spec.scm" files in the source tree to see the
scheme<->C bindings;
http://svn.gnucash.org/repo/gnucash/trunk/src/engine/gw-engine-spec.scm
is an example.

There is a hello world report, yes.
http://svn.gnucash.org/repo/gnucash/trunk/src/report/utility-reports/hello-world.scm
