How to implement simple GUI login and registration interface in Java

The implementation code is as follows:

1. Login interface

package cn.bms.view;

import java.awt.Color;
import java.awt.Dimension;
import java.awt.Font;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

import javax.swing.ImageIcon;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.JTextField;
import javax.swing.border.MatteBorder;

import cn.bms.tools.GUITools;

/*
