    Default need an interface for a recursion algorithm program

    i need some help to finish my assignment
    following is the code
    i want the main method to get an user input, it should be a GUI, since i don;t know swing i find it hard , please help me.. regards.. i want the interface to get a single integer and buttons to compute, factorial, triangle and partaily by giving a nother value to compute permutation or combination

    import java.io.*;
    class fcp
    {
    int factorialGen(int x){

    int temp;
    if(x==0){
    temp=1;
    }else if(x==1){
    temp=1;
    }else{
    temp=x*factorialGen(x-1); //recurtion of function;
    }
    return temp;
    }

    int combination(int n,int r){
    int x = factorialGen(n)/(factorialGen(r)*factorialGen(n-r));
    return x;
    }

    int permutation(int n,int r){
    int x = factorialGen(n)/factorialGen(r);
    return x;
    }

    void triangle(int x){
    for(int n=0;n<=x;n++){
    for(int j=x;j>=0;j--){
    System.out.println(" ");
    }
    for(int r=0;r<n;r++){
    combination(n,r);
    }

    }
    System.out.println("\n");

    }

    void pascalTrianglefactorial(int x){

    System.out.println("The factorial value is"+factorialGen(x));
    triangle(x);
    }

    Default

    Create JFrame ,add to it JPanel which will have JButton and JTextField,and add to the action listeners,which will produce and operate all the functions you need.
