What to learn to create a desktop application interface?

Question

User interface

Hello! Prior to that, I was only doing web development with Django. But the following task appeared:
Create a desktop application to interact with the REST API. The application must have the following functionality:
- Take information from the server via API, parse it and display the table;
- Form for adding a record to the database via API
- Connecting a barcode scanner.

Since I was programming in Python before, I looked at PyQT5, but as far as I understood, it’s unlikely to draw a normal interface there. What would you recommend learning to create such an application? (Preferably in Python, but if it is impossible to make a normal beautiful interface on it, then it is possible on other languages)? Are there technologies for creating an interface on CSS styles and should they be used?

Answer 1

Slack, Skype, Discord are written on Electron...
if you don't use frameworks on the client, it will work smartly

Answer 2

Look towards Delphi and cross-platform framework FMX. Styling there occurs not by code (especially not by CSS), but by rivers, visually. You can see examples here https://www.youtube.com/channel/UC-IUzlqieYIqv5vFI... or here https://vk.com/delphilive
