Is there a way to open a browser-based editor (e.g. CKEdit, tinymce, or any other HTML + JavaScript editor) in a Python window (possibly wx.Python), and not in the browser? Thank you in advance.
I suggest you try using python Webkit bindings. You can download a custom Webview and place it anywhere as a GTK widget:

I am not sure about WX.
One difficulty you will find is how to get values ββfrom JS in Python.
Here's an article describing the trick for invoking isolated JS from Python:

Good luck
