In both cases there's a many-to-one relationship; one schematic can be
used for many purposes, and one pcb is made of many schematics.

So gschem would have to have many buttons, one for each purpose the
schematic is used for, but pcb would only need one - to collect the
things it needs.  PCB's File->Import does this; it knows how to use a
list of schematic pages or call out to a Makefile to get what *it*
needs.  A "getting started" button on gschem would need to assume that
the one schematic is sufficient for one pcb, or figure out how to ask
the user what other schematics are needed.  Also, not everyone starts
a pcb with the import - I prefer to lay out the board's boundaries and
physical size first, *then* import.

BOMs are trickier, because you need to know the set of schematics but
you also need to know the build-out of the board, i.e. which
configuration of parts is populated.  I typically use a script to
generate a BOM from schematics on a per-pcb basis, using attributes
from the schematic, but I can't see that working as a button in either
gschem or pcb.  Also, if your sch->pcb tool modifies any of the parts,
the BOM generator would need to know about that too.
