Using a C++ library from C or scheme

[Christian Stimming]

Oh well, I found some resources on using C++ objects from C: 
http://www.parashift.com/c++-faq-lite/mixing-c-and-cpp.html#faq-30.8 and 
since I have development access to the c++ library this is probably the 
way to go.  Or does somebody have more experiences in how well this works?

Or are there some opinions on whether GUI stuff in gnucash can be coded 
easier in Scheme versus in C? Related to Scheme wrappers of a c++ 
library I saw SWIG somewhere on the net. So maybe it's quite easy for me 
to provide scheme library access as well... does somebody know of 
possible caveats there?
