To date (2013 05 09) the readme.rst in repo and the 0.9b download are outdated:

1. tells "gui2py requires Python 2.5 or later (up to 2.7)" so no mention that it runs on python 3+

2. tells "gui2py requires ... and wxPython 2.8 or later. wxPython 2.9.4 is required to use the newer features (PropertyGrid, WrapSizer, etc.)"

should also tell that wx 2.9.4 (or whatever) is required to run the visual GUI designer: it tracebacks with wx version '2.8.12.1 (msw-unicode)':

D:\tmp\gui2py-0.9b>py -2 -m gui.tools.designer Traceback (most recent call last): File "C:\Python27\lib\runpy.py", line 162, in _run_module_as_main "main", fname, loader, pkg_name) File "C:\Python27\lib\runpy.py", line 72, in _run_code exec code in run_globals File "D:\tmp\gui2py-0.9b\gui\tools\designer.py", line 531, in <module> from gui.tools.inspector import InspectorPanel File "gui\tools\inspector.py", line 16, in <module> from gui.tools.propeditor import PropertyEditorPanel File "gui\tools\propeditor.py", line 17, in <module> import wx.propgrid as wxpg ImportError: No module named propgrid

Si, si, ya actualizo Mariano, es solo para avisar.
