CRUD system for a CRM using RDS in AWS

I need to do the following:

1. Create a DB (I have created the DB with AWS - RDS)
2. Import existing data from an excel spreadsheet into said DB
3. Create a GUI for CRUD operations

What would be the most streamlined way of approaching 2 and 3? Any help pointing me in the right direction would be much appreciated!

I have tried using Django but I ran into so many errors from the start, so looking to see if there is a better way to implement this.

(preferably scripting in Python)
