advice getting started with GUI project

[loulou]

hello, I have started an internship in which I was told to create a GUI in python which would consist of diagrams and templates as well as amendable information. Being new to programing in general, I was wondering what the best way to go about creating this GUI was. I already have a vision in mind for how it should look/work but I don't know how to begin the task of programming.

Are there any templates available which can then be edited to suit my own vision or do I have to start from scratch?
I was also wondering which GUI toolkit module I should use, with simplicity and aesthetics being the main criteria, any recommendations?

thank you
