Quick and easy Java Swing work using JTree/JTextArea/JLabel

Thank you for helping, I am a Python scripter trying to teach myself recursion! I need a single JPanel with JTree, JTextArea, JLabel, and JButton widgets. 1. On init, JTree loads the XML structure from file on disk (example file attached). Create a recursive method that parses the XML and populates the JTree with the nodes appropriately nested. 2. Create a right-click menu in the JTree to create new nodes. Capture the mouse hit/click location and create a popup menu with the options "Create Folder" and "Create Revision". Each of these options should have an event attached to fire a method that creates a new node of the specified type and adds it to the JTree. The new node should be created at the mouse hit location, either above or below the existing node closest to the mouse hit/click. 3. Create a method that converts the existing JTree structure to XML, and then writes the XML to a file on disk. Create a button with an attached event that fires this method. 4. Create an event where clicking on a child node in JTree updates JTextArea and JLabel widgets with that node's data, e.g. clicking one of the "Revision" children should place the text "This is...revision" in the JTextArea, and also place the node's revision version number in the JLabel.
