功能：实现一个计算器应用程序 实验要求：编写一个模拟计算器的应用程序，使用面板和网格布局， 添加一个文本框，10个数字按钮（0~9），4个加减乘除按钮， 一个等号按钮，一个清除按钮，一个求平方根按钮，一个退格按钮， 要求将计算公式和结果显示在文本框中，实现效果如下图所示，(Functions: a calculator application requirement of experiment: write a simulation calculator applications, the use of panels and grid layout, add a text box, 10 numeric buttons (0 to 9), 4, Math button, a equal sign button, a Clear button, a square root button, and a backspace button, the formula and the results are displayed in the text box, as shown in the results as shown)

Xlet will be visible on-screen, so we extend org.havi.ui.HComponent(NOT java.awt.Component). it also implements java.awt.KeyListener to receive keypresses an RCU
