What are the tools for creating simple admin panels?

Question

API

There is a backend server written in Java. Communication with him occurs through the REST api.
It is necessary to write a simple admin panel that could interact with the server. Namely: send requests to the server, receive a response, and, based on it, display information to the user. You also need to be able to edit and add the necessary information.
Help me find a tool that would help to implement this in a relatively simple way.

Answer 1

Take Angular / React or Vue and cut your admin panel using some kind of AdminLte.

Answer 2

Laravel + GuzzleHttp for example. Easier nowhere.

There are a million templates here - we took them from here. There are paid good ones, free ones are so-so. React/Angular - whatever.
