The way this is done depends on whether you are using 1.4.x or
the development version. Either way, looking at the wrapped
engine API in src/guile/gnc.html is helpful.

For both versions, you can add a menu item whose callback invokes
a scheme thunk. See src/scm/extensions.scm. For the development
version, you can also specify a scm file to load with --load.
