Strictly speaking no GUI can be written using only a programming language like perl, java, tcl... I/O has nothing to do in the discussion comparing Turing Complete vs. "supporting some language feature in a way that makes it practical for humans to use it.".

What is a programming language other than a language for creating instructions for moving pieces of matter around? You could do this with Java if you give it the same physical resources that the current graphics pipelines have. That stuff isn't exposed to Java and would be pretty cumbersome to manipulate with Java, but it can still in principle be done.
