用java做QQ登錄界面的寫法如下：
專注于為中小企業(yè)提供成都網(wǎng)站建設(shè)、網(wǎng)站建設(shè)服務,電腦端+手機端+微信端的三站合一,更高效的管理,為中小企業(yè)新建免費做網(wǎng)站提供優(yōu)質(zhì)的服務。我們立足成都，凝聚了一批互聯(lián)網(wǎng)行業(yè)人才，有力地推動了上千企業(yè)的穩(wěn)健成長，幫助中小企業(yè)通過網(wǎng)站建設(shè)實現(xiàn)規(guī)模擴充和轉(zhuǎn)變。

1、//定義該類繼承自JFrame，實現(xiàn)ActionListener接口
public class LoginTest extends JFrame implements ActionListener
{
2、//創(chuàng)建JPanel對象
private JPanel jp=new JPanel();
3、//創(chuàng)建3個標并加入數(shù)組
JLabel name = new JLabel("請輸入用戶名");
JLabel password = new JLabel("請輸入密碼");
JLabel show = new JLabel("");
private JLabel[] jl={name,password,show};
4、//創(chuàng)建登陸和重置按扭并加入數(shù)組
JButton login = new JButton("登陸");

5、//創(chuàng)建文本框以及密碼框
private JTextField jName=new JTextField();
private JPasswordField jPassword =new JPasswordField();

jp.add(jl[i]);
jp.add(jb[i]);
//為2個按鈕注冊動作事件監(jiān)聽器
jb[i].addActionListener(this);
}
9、//設(shè)置文本框的位置和大小，注意滿足美觀并足夠用戶名的長度

用java是可以寫出qq的，只不過用java開發(fā)c/s的軟件不是java特長的，你要是真的想寫，就寫著練練手吧，最起碼可以鞏固java se上的知識。
具體怎么寫，給你個大概的思路吧，因為我沒辦法在這個有限的輸入框內(nèi)把所有的代碼寫完。
【1】先寫出qq的簡單界面
【2】給每個按鈕添加監(jiān)聽
【3】按鈕事件（方法）定義
【4】連接網(wǎng)絡（socket）
【5】測試
【5】其他功能添加
【6】測試
