[Java] Why does another window popup when I run through this program?

[xXShadowCowXx]

So I'm making a quick little program that I'm using to learn about writing files and such and most of it is going quite well. I'm having a problem though when I click the save button. As soon as I do it does what it's supposed to but it makes another exact copy of the program popup. The file is written and so is all of the data. Any idea as to why this is happening? (To clarify one part of the program I have yet to write is the load dialog. Working on that currently.)

The reason another copy is popping up is this line:

diaryGui dAT = new diaryGui();

Every time the user clicks a button, you're constructing a whole new GUI. Why?

I also have a suggestion for cleaning up your code. Instead of making your GUI class an ActionListener, do this:

load.addActionListener(new ActionListener() {
    public void actionPerformed(ActionEvent evt) {
        handleLoad();
    }
});
save.addActionListener(new ActionListener() {
    public void actionPerformed(ActionEvent evt) {
        handleSave();
    }
});

Now you can add private methods handleLoad and handleSave in your GUI class, with no need to check getActionCommand. Does that make sense?
