I was wondering if someone has tried to develop a graphical use interface for EnergyPlus input file manipulation? This can be be used to just click and change some of the fields/objects within idf file. Also, this can be extended for model calibration purposes. I have heard a lot about Eppy as a brilliant EnergyPlus IDF file text manipulation library but wondering if anyone has given a try to extend this and develop a GUI? Also, do you have any recommended python libraries than can be used for the development of GUI?

EDIT:

Sorry I did not clearly ask my question, I know there are many GUI for EnergyPlus. I have to write some script to automate or semi-automate calibration process (I know there are also calibration tools available for this purpose but I have to do it for a project). I can do this by using Eppy library but was wondering what if in future I want to extend this and develop a GUI for scripts then what are the available options of libraries or if anyone has experience of doing this?
