> how do you draw a window with a editable text field inside,
No idea what you are talking about. You don't draw a window. You create a JFrame and then you add components to the frame. These components can be menus, toolbars etc.

>That didnt help, can someone just explain how to create a J TEXT FIELD....
Even though you might not belive it; Google is your best friend! use it. Search for: JTextField tutorial.
This is the first result you get: http://java.sun.com/docs/books/tutorial/uiswing/components/textfield.html
Have a look around there and eventually you might find this link: http://java.sun.com/docs/books/tutorial/uiswing/components/examples/TextDemo.java
Which contains an example which you are intressted in.
This is the best and probably only way your gonna learn about java, through the internet, if not through school will say. So if not for the last option then use the internet like most people do.
