I think what he was asking was, could there be some way of packaging a .exe with a full python environment and all dependencies built in (and so zero install basically)?

Edit: after reading the docs for pyinstaller, it seems that this is exactly what it does. vxNsr was either confused about what gooey does, or, like me, got confused by the name "pyinstaller" and assumed it was a tool to help you install a python environment on Windows.
