Several people have created scripts to parse header files and automatically produce Cython bindings.
xdress
XDress is an automatic wrapper generator for C/C++ written in pure Python. Currently, xdress may generate Python bindings (via Cython) for C++ classes & functions and in-memory wrappers for C++ standard library containers (sets, vectors, maps). In the future, other tools and bindings will be supported.

cython-codegen
The is a tool called *cython-codegen* or *xml2cython.py* written by David Cournapeau - download it with git (a version control tool, apt-get install git):
git clone http://github.com/cournape/cython-codegen
It requires gcc_xml and codegenlib from ctypeslib (apt get install python-ctypeslib)

pxd-gcc-generation
Philip Herron's 2012 GSoC project, using GCC plugins to generate pxd files. Code at
https://github.com/robertwb/cython/tree/pxd-gcc-generation
Requires a recent version of gcc and gcc-python-plugin.
