A quick, rather goofy, desktop WebKit wrapper w/ Qt/Pyside.

phonegap-pyside.py

#! /usr/bin/env python
import sys
import os

from PySide.QtCore import *
from PySide.QtGui import *
from PySide.QtWebKit import *

app = QApplication(sys.argv)
app.setQuitOnLastWindowClosed(True)

www = os.path.join(os.path.dirname(__file__), 'www', 'index.html')
web = QWebView()

web.resize(100, 300)
web.setWindowTitle('hello world')
web.load(QUrl(www))
web.show()

sys.exit(app.exec_())
