I have an ANSI C++ code library for parsing Nexus file format. I'm interested to create relatively simple GUI application, which has to use the underlined library. I need such an application to run on MacOS. I've never programmed on MacOS or for MacOS. I have a VC++ 6.0/.NET versions of such application. Please suggest solution/s for either translating the application to be able running on MacOS or for creating a new GUI based application, using ANSI C++ code.
I'll be much appreciated for any help,
