This could be problem with libc or gtk, is it ok if I can make offline webapp built using flask ?

[AshokR]

Hi kracekumar,

We want to be able to create a stand-alone application that will run on
Windows/Mac/Linux. Arunmozhi created the app using wxPython. At the
suggestion of Mugunth, I changed it to PyQT4 (modified from Benjamin
Thyreau's code). I am not familiar with flask. However, looks like it is a
web app framework. If it can be made to work offline, and we can create a
Windows install file, I think that should work.

I am copying Mugunth in this email for two reasons:

1. I understand Mugunth is working on QT. He may be able to help resolve
   this issue.
   2, He can guide you on QT vs flask.

Regards,
Ashok

Thanks for the reply. I can help on porting the application to Flask. @mugunth Recently kivy has gained lot of momentum, it can run on mobile phones as well.

[AshokR]

A lot more people have access to a mobile phone than a PC. So, if kivy can
run on mobile phones as well, my vote is for kivy. Mugunth?
