Using a C++ library from either C or Scheme

Hi Rob or anybody else,

I'm about to start working on implementing HBCI support in Gnucash. (HBCI = 
German online banking protocol standard.) 

Fortunately enough, other developers from Germany (most notably Martin 
Preuss) have finished a library that encapsulates all the ugly protocol 
programming. I will definitely want to use their library for accessing the 
HBCI actions. Now, the library itself is written in C++ ... and thus I 
somehow need to access C++ from Gnucash. I'd like to hear your opinions on 
how hard it would be to access C++ from either C or Scheme (both languages 
would work just fine for me). And/or does there happen to exist any g-wrap 
support for C++?

Also, does anybody know any resources and/or tutorials and/or examples on how 
to wrap the C++-library best into C or Scheme?

Thanks a lot.

Christian
