Boa Constuctor 0.2.3 can be downloaded from SourceForge here.

Before this can work, you'll need to have successfully installed wxPython or higher and Python 2.1 or higher.
If you want wxPython/Python help integrated with Boa, you'll also need to download it from the SourceForge files page.
Boa cannot use the .chm files included with the wxPython windows installer.
