Even if your PIC program is written in C or PicBasic, the I/O is not directly translatable. C is standardized, but PicBasic is not so there's no equivalent compiler. It would be possible for someone to write a set of I/O drivers to try to emulate the various functional I/O units, but you'd have to find someone and pay them for their time and effort to do so and, even then, there would likely be some differences.
