Vaadin client compiler vs. GWT compiler

For client-side widget development the Vaadin client compiler is used.

The Vaadin client compiler is ‘based’ on the GWT compiler.

hat being said, would it be correct to say that “GWT is used for compiling a widget set”

Yes, vaadin is using the GWT compiler directly (com.google.gwt.dev.Compiler).
