Hi. I'm not entirely clear what you mean by "CGI Script for cpp code". Do you mean you need a CGI web interface implemented in the C++ language?
If so, I would be interested in investigating this for you. I have written CGI in the C language before, and have worked a lot with CGI in Perl also.
I may need to revise my bid based on the details you provide.
I do my development on Linux - using the GNU C/C++ compiler.
I am in Ireland - so GMT timezone (a few hours ahead of Canada).
