swing and binary trees

I'm working on a program for class where I have a binary tree that i coded myself. When I do a print on the binary tree it steps down the tree and prints all the nodes. When it gets to a node it prints that node.

The problem arises in my main class where I create my main frame and buttons used in the program. I'm trying to make it pop up a new window that prints the data contained in the tree. I was doing this previously to the command line with System.out.println().

Is there a way to find the mainframe, attach a frame to that and print out the courses their? Is there something comparable to the println for swing? I can provide more info if needed. Thanks.
