title: How to write Eclipse BUILT in GUI
body: <p>so please help me out.</p>
  
  <p>So I have been creating GUI using AWT and SWING in java eclipse. 
  Currently my program creates pop-up windows for the UI, with the use of JFrame and such. </p>
  
  <p>I recently learned that I can create UI that is integrated in Eclipse itself. 
  and doesnt need to create another window. </p>
  
  <p>Is that a eclipse plugin? I am brand new to this, so please let me know where i Can learn this or if you guys can share your knowledge. </p>
  
  <p>Just to make sure you guys understand, i would like to link an image. 
  But just to describe, on the tabs in eclipse (TOP) where is hows the file opened currently, I want to e able to write code that opens a tab their with UI in it instead of code.</p>
