How did they create windows? using what programing language? how about MacOS?
 
As for Windows - mostly C/C++ and assembly for the low-level stuff (like device drivers etc.)the bulk of the code was originally written in Cobol, but was quickly moved to C in the early 90s. Today C++ is the language of choice for any unmanaged code in Windows.
 
I know that Windows 98 is created using QBASIC, Windows 2000, Windows Xp, Windows 2003 etc are created using VC++.Now all the coming versions of Windows will use .NET , especially VC# .NET.
 
You CANNOT create a OS with QBASIC or VC++, the OS kernels are commonly written in C/C++ and Assembly, components of a OS is created by C/C++, but it is not important which language is it because if you can assemble it natively for the processor, you can code an OS, but QBASIC and VC++ CANNOT be assembled to run on a pure processor, because both of them uses API's and they designed to create programs for Windows operating systems.
