Below are instructions for building a Windows installer for Diffuse.
Prerequisites:
1) Python >= 2.4
http://www.python.org/
Python 3.0 has not been tested as no official PyGTK package for Python 3.0
has been released at the time of writing.
2) PyGTK >= 2.10
http://www.pygtk.org/
PyGTK has its own set of dependencies. GTK+ runtime, PyCairo, and PyGObject
should be installed in that order prior to installing PyGTK. If the GTK+
runtime installer did not set the GTK_BASEPATH environment variable,
manually set it to the installation path. Also, add the 'bin' and 'lib'
directories to the PATH environment variable.
3) py2exe
http://www.py2exe.org/
4) xsltproc (use Cygwin installer)
5) docbook-xsl (use Cygwin installer)
6) ADD_PATH
http://blog.barisione.org/projects/#add_path
Unzip the package and set the environment variable ADD_PATH_HOME to the full
path of the root directory.
7) GNU gettext (use Cygwin installer; install the development package)
8) Inno Setup

You may need to manually update the PATH environment variable to run
ISCC.exe from the command line.
Building the installer:
After all of the prerequisites are installed, run the build.py Python script to
create a Windows installer for Diffuse. If successful, an installer will be
created in the current directory named diffuse-{version}.{platform}.exe.
