first I am a new to java You should learn the standard Java naming conventions. Basically variable names and method names should be mixed lower/upper case on each word:
windowFrame -not WindowFrame
buildMenuBar() - not BuildMenuBar()
For class names you do upper case the the first character of each word.
Your code is confusing to read since everything is upper cased and therefore looks like a reference to a class.
