Is it possible to have a Python application with a GUI (such as TkInter or WxPython) with :

* a Chrome browser as a widget using the main part of the GUI, displaying a certain .html page
* **be able to save files locally thanks to Javascript that is run in the embedded Chrome** (that is normally impossible with any browser for security reasons)

If it's not possible in Python, I'm open to use another language (C++, etc.).
