GUI with basic functionality options

[yugeshk]

Writing a GUI using PyGTK or PyQt with selections for doing simple tasks like selecting file for encryption, decryption, etc.

It is important here that the GUI not freeze while one task is under way. some blogs on PyQt include how to manage this.

@sourabhtk37 What library would you recommend for the GUI? I have worked with PyGTK, but more recently people have been recommending PyQt.

PyGTK is phased out in favour of PyGObject and GTK+3 (here).

Regarding PyQt, it have tons of features that you and I are probably never gonna use 😄 .
But Qt company recently made an announcement and also which makes PySide2(another Qt binding for python, works very similar to PyQt) offical python binding of Qt framework (means more support and maintenance than PyQt4/5 by riverside computing.)
But it's doesn't yet have a stable release yet.

Since, you have experience with GTK, "my recommendation" would PyGObject and GTK+3.
