homework to create calculator using JAVA.

Hi I have a homework to create calculator using JAVA. I found a code in chegg but it is not complete, I need someone to create me these classes to complete the code. NumPanel, OperationsPanel, ConversionPanel, and RadioButton. The partial code and homework instructions are attached below. And I'm using Eclipse to compile it.

import javax.swing.*;
import java.util.*;
import java.awt.BorderLayout;
import javax.swing.GroupLayout;
import javax.swing.GroupLayout.Alignment;
import java.awt.event.*;

public class CalculatorFrame extends JFrame implements ActionListener{

   // INITALZING VARIABLES
   ResultPanel resultTextBox; // this displays the results
   NumPanel numPad; // this holds the number buttons
   OperationsPanel opPad; // this holds the operations buttons
   ConversionPanel conTextBox; // this displays the converted text
   RadioButtonPanel radioPad; // this checks what button is pressed to see what to convert
   char operation; // this tells us what operation is being used
   String num1, mSaved; // these are for memory and operation related stuff
   int saved;
   int addClicked, subClicked, multClicked, divClicked = 1;

   ////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////

   CalculatorFrame(){

       ////////////////////////////////////////////////////////// RESULT PANEL ///////////////////////////////////////////////////////

       resultTextBox = new ResultPanel(); // creating object textBox
       add(resultTextBox, BorderLayout.NORTH); // add the textBox NORTH of the Window

       ////////////////////////////////////////////////////////// CONVERSION BOX /////////////////////////////////////////////////////

       conTextBox = new ConversionPanel(); // creating object conversion text box
       add(conTextBox, BorderLayout.SOUTH);

       ////////////////////////////////////////////////////////// NUMBER PANEL ///////////////////////////////////////////////////////

       numPad = new NumPanel(); // create the object for the numberPad
       add(numPad); // add the numberPad

       GroupLayout gl_numPad = new GroupLayout(numPad); // create group layer for numberPad
       numPad.setLayout(gl_numPad); // set the numberPad to the group layer

       gl_numPad.setHorizontalGroup( // setting horizontal alignment
               gl_numPad.createParallelGroup(Alignment.LEADING) // always need this
                   .addGroup(gl_numPad.createSequentialGroup() // make a row of bs, c, ce
