Seeking tool to generate skeleton C++ code from header files

[Baron Samedi]

I am looking for a (free) tool which takes C++ Header files as its
input and generates skeletons for the corresponding source code.

Just empty functions are acceptable, but a templating system would be
welcome.

Preferably something that runs under windows, but I could always use a
Linux Live CD, as I only expect to do this once.

Thanks in advance
