Java: Design the program implementation separate from the GUI?

Question

I have learned a fair amount of Java (for a beginner) and have started making a few complicated engineering-type programs which work well from the command-line interface. (As a background: I originally learned programming with Fortran -- so command-line is the level I know best). 

I am now trying to implement some GUI interfaces to my programs.  But my implementation code seems to inevitably get interweaven (i.e. buried!) with GUI code, so I lose all oversight.

Any suggestions or known tutorials that specifically address how to write one set of Java classes that do the GUI, another set of classes handle the implementation and cleanly link them together?  Oher suggestions of how to learn to tackle this Design issue?? 

Thanks.

You want to use a design pattern known as model-view-controller, which separates the code that creates the GUI (the view) from the code that reacts when an action is performed (the controller) and the underlying code that it controls (the model). It's a very useful and widely used pattern so there's a lot written about it online. I found a few articles on the Sun website to start you off.

Go through the Java tutorials on Sun's website. The examples have the GUI in completely independent classes, so it's easier to comprehend. That's how I learned about GUIs.

Go to the link in the sources, and then look at the examples that they give for the features. Most of them are doing what you are saying you want to implement.
