Mac is Unix under the hood. On Windows you can install Linux in a virtual machine, or you can install Cygwin (which is basically an almost complete POSIX system on Windows). You can use your preferred programming language to implement any of these tools: Ruby, Python, Perl, Scheme, Common Lisp, C, C++ ... The original Unix implementation of these tools was done in C.
