Problem with form, Window Builder Eclipse

I am trying to create a form to register a user using the Window Builder plugin with Eclipse, compile but at the time of entering the data and clicking on the "register" button, all the errors appear. The program does compile, but when you open the window and hit the button it does not work and errors appear in the console.

EDIT: All these errors appear to me.
