Create Windows interface for DOS program

This should be a fairly simple project. I have a DOS-based program that was written in C. I'd like to create a Windows-based interface to make it easier to use. The interface can either be added to the C code, or the program can be rewritten in VB. The program converts pdb (palm database) files to plain text files. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Installation package that will install the software (in ready-to-run condition) on the platform(s) specified in this bid request. 3) Complete ownership and distribution copyrights to all work purchased. ## Platform Windows
