You might want to look into the Dynamic FFI section of the Guile Info
manual: (info "(guile) Dynamic FFI")

Web version:
http://www.gnu.org/software/guile/manual/html_node/Dynamic-FFI.html

In summary, you can get pointers to Guile procedures via
'procedure->pointer' ('scm_procedure_to_pointer' in the C API).

Working with complicated struct types might be somewhat uncomfortable,
and I'm working on https://github.com/taylanub/scheme-bytestructures to
solve that, but I haven't worked on integrating it with the FFI much
yet.  On the meanwhile there's (info "(guile) Foreign Structs").

Web:
http://www.gnu.org/software/guile/manual/html_node/Foreign-Structs.html

You might also want to go through the rest of the FFI chapter of the
manual to see if there's anything useful for you:
(info "(guile) Foreign Function Interface")

That's my limited knowledge.
Hope it helps,
