I'm using NCBI's toolkit now, and it is good.
Use NCBI's kit if you want cross-platform compatibility *now*, at no
cost but for a C compiler. NCBI's kit is in C.
If you prefer C++ (I think most people will find C++ faster to write
to than C), I'll have a C++ application framework source
out in a week or so that wraps around NCBI's kit.
See ftp.bio.indiana.edu in /util/dclap for some example applications
and info. There are still plenty of bugs in my c++ framework, but
NCBI's toolkit is pretty solid. It took me one weekend to get
things working for mswindows after having done the mac & xmotif basics.
I haven't written any really platform specific code, as their toolkit
covers all of that. It is solid, and after some time spent learning
what is in it, no problem to use.
