Hi I want to create a simple odoo module which will run a simple python script and download a file from database. The script consist of a sql command to download data from tables. I want to export that data to a csv file.

But i am beginner at programming and doesnt know how to create that module via programming. Can we create a module from frontend? I have seen options to create model and views from frontend. Also if someone can guide me through the process.

EDIT : I have read the documentation and the example given (Open academy) is created on backend via programming. I am looking for something simpler like create a model and view from frontend and attach a python script to it. I just want to export some data from postgres databse to a csv file.

PS: I created a menu item by creating a model first and then creating a menu from that model. I am stuck at how to add a python script to that menu so that it can export data from a table to csv file. I just need a button which runs that script. No extras.
