Is Any Free Ware Interface Programming Software For Windows?

Is any free ware software for computer interface programming, like to code interface of an electronic device to Windows? I used to do interface programming using Borland C++ (the command version) and Borland C++ Builder (the graphic version) around 20-15 years ago. But I am not sure whether that software still working on newest Windows (Windows 10). I myself still using Windows Vista. Unfortunately like no more Borland right now. So, look like I lost my trace.
