 "its" not "it's".  "it apostrophe s" is short for "it is".  so you've
said "i created an app that all of it is interfaces were actually web

 well, if you want to run python under wine, and attempt to install
pythoncom-win32 under that, i _have_ had some success in getting
python 2.5 to work as a wine application, and worked with the wine
team to fix a number of critical bugs in the not-exactly-posix-
compliant MSVCRT.

 so you _could_ conceivably get that up and running, and it would be
_kinda_ cross-platform.  don't even think of using python 2.7 yet
because changes in python 2.7 make extensive use of message-mode
NamedPipes, and the wine NamedPipes infrastructure doesn't support
message-mode, and so screws up on critical things like the thread

 yes.  so, therefore, you need to look at python-hulahop or
pywebkitgtk with patch #13 and webkit-glib/gdom (webkit with patch
#16401, or use my pre-patched tree - http://github.com/lkcl/webkit/tree/16401.master

 you're not asking too much - you're just asking for a whopping great
30mb of dependencies, whichever way you go.

 if you'd like to help out, we _really_ do need builds of webkit for
win32, patched, which took a week, last time i tried - see

 and then win32 builds of pywebkitgtk on top of _that_.

 either way, if you go the python-hulahop or the pywebkitgtk-patched +
webkit-patched route, you're in for about two weeks non-stop of
build / compilation / dependency-hunting, to get something going on

 as i've done webkit-win32 once before, i will be in a position to
help advise you (and the bugs in gcc i encountered will likely have
been fixed by now in "official" releases).

 whereas the python-hulahop build process you're likely to be the
first person ever, in the world, to try building python-hulahop for
