一个Java 拿火柴小程序 求那位大虾帮做个图形界面

Question

马上要交作业了，临时学的话 不太现实 所以求助中，如题。
实现了程序向随机生成20到50根火柴，由人或者计算机轮流拿，每次拿的数量不超过3根，拿到最后一根算胜利。
程序如下
import java.io.*;
public class huochaiyouxi{
    public static void main (String args[])throws IOException{
        int a=10,remain,p=0;
        System.out.println("拿取火柴的优先权选择模式，输入1为随机选择,任意输入非1的整数为自主选择：");
        BufferedReader s=new BufferedReader(new InputStreamReader(System.in));
        int n=Integer.parseInt(s.readLine());
        while(n>0&&n<2)//机选
        {double k=(double)Math.random();
        if(k<0.5){
        a=0 ;--n;}
        else if (k>0.5)
        {a=1 ;++n;}
        else 
        n=1;
            }
    if (a<11&&a>9)//人选
    {System.out.println("请输入1为机器优先，输入0为玩家优先：");
        BufferedReader q=new BufferedReader(new InputStreamReader(System.in));
        int m=Integer.parseInt(q.readLine());
        a=m;
        }//确定了a的值，        
        int amount=(int)(20+Math.random()*31);//开始确定火柴
        remain=amount;
        System.out.println("火柴的总数为："+amount);
        while(remain>0){for(int k=1;k<=remain;k++){//拿火柴程序
            
                System.out.print("i ");}
                System.out.println();
            if(a<1){System.out.println("剩余火柴数量为："+remain);
                System.out.println("请输入您要拿走的火柴数量至少拿1根，最多拿3根：");
                BufferedReader w=new BufferedReader(new InputStreamReader(System.in));
        int z=Integer.parseInt(w.readLine());
        if (z>0&&z<=3) {
        remain=remain-z;
        if (remain>0)
        a=1;
        else
        a=0;
        }
        else System.out.println("注意拿取火柴的数量至少有1根，最多拿3根!!!!");
                }        
        if(a>0){
             if(remain%4==0)
             p=(int)(1+Math.random()*3);
            else
            p=remain%4;
            remain=remain-p;
            System.out.println("电脑拿了"+p+"根。");
        if (remain>0)
        a=0;
        else
        a=1;
            }
            }    
            /*确定胜者*/
            if(a>0)
            System.out.println("电脑获得了胜利！");
            else
            System.out.println("恭喜您胜利了！");    
                }
                }
