One particular program would could write in Python is called a "C++
compiler".  While this would not be a particularly *easy* program to
write, you *could* write a script called 'gcc.py' that took all the same
arguments and input *data* files as a program called 'gcc', and produced
as a result bit-identical outputs.  This may be a somewhat cumbersome
approach to writing a device driver in Python, but...
