First individual java project, help to get started

Question

Hi first of let me introduce myself,
I am Koos, 16.75 years old and from Holland. At school we are learning or suppossed to learn java language, that's how I got interested in java, anyway it isn't going that great so far.
But I already created my first assignment a tool which counts the letters in a word, in a JFrame of course to make it look better.
I use Eclipse to program java (what is in you opinion the best program to program in java?) and have of course installed the JDK.
Now to get to the point, I want to contribute to a site I often visit to make a java calculation applet.
The main Idea is to make a new window where calculations are done by multiple inputs and outputs. It's doing some simple maths such as percentage, division and multiplication.
I would like to implement different data (different currency (Eur,Usd,Gbp) and pairs(EurChf,EurGbp GbpChf and UsdCad), and then all options possible,
from [this tool|http://www.goforex.net/pip-calculator.htm] , could that be possible to automate or is it better to manually put in?
I will update in an hour or so with a formula, if you would like, I already have the principal in excel so I could upload that if you'd like that.
Regards,
Koos

Hi I have written the part for the window and the input fields but the fields don't show up what's wrong in the code?
import javax.swing.*;
public class Window extends JFrame {
     public static void main(String[] args){
          new Window();
     public Window() {
     JFrame frame = new JFrame("Fapturbo LRR calculator");
          this.setSize(500, 400);
          this.setVisible(true);
          this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
          JPanel area = new content;
          this.setContentPane(content);
          this.setVisible(true);
          this.setLocationRelativeTo(null)
class content extends JPanel {
     private JLabel Lotsriskreduction,equity,priceEURGBP,priceEURCHF,priceUSDCAD,priceGBPCHF;
     private JButton Calculate;
     private int inputLRR,inputEQ,inputP1,inputP2,inputP3,inputP4;
     private JTextField input1;
     public content() {
          this.setLayout(null);
          input1 = new JTextField();
          this.add(input1);
          input1.setBounds(24, 80, 210, 20);
          /// Here comes the calculation folowing the formula I posted before including their outputs/
          //in the same kind of field as the input.
          Calculate = new JButton("Calculate");
          Calculation kh = new Calculation();
}regards,
Koos
