Can a Java GUI manage a Python backend?

Question

Ok, so I still have gui (In Java) and a program (In Python). I want the button in gui to be pressed in order to send the outputs to the python program and run it. Then I want the gui program to display python print commands in the text box on the right.

So my question is: is this possible and how can I make it work?

You can start the python process:

 Process p = Runtime.getRuntime().exec("python "+yourpythonprog+" "+yourargs); 

Then use the Process object to read the output of your python program.
