Customizing GUI components in Java applications is a crucial aspect of creating user-friendly interfaces that meet specific user requirements. This customization can be achieved through various techniques such as subclassing, property modification, and styling.

1. Subclassing: This involves creating a new class that inherits the properties and methods of an existing GUI component class. The new class can then override the inherited methods to provide custom functionality. For example, you can create a subclass of the JButton class in Swing and override its paintComponent method to change the button's appearance.

```java
public class CustomButton extends JButton {
@Override
protected void paintComponent(Graphics g) {
// Custom painting code here
}
}
```

2. Property Modification: This involves changing the properties of a GUI component to alter its appearance or behavior. For example, you can change the background color of a Swing JButton using the setBackground method.

```java
JButton button = new JButton("Click me");
button.setBackground(Color.RED);
```

3. Styling: This involves applying styles to GUI components to change their appearance. In SWT and JFace, you can use the setStyle method to apply styles to components. For example, you can set the style of a Button to push like this:

```java
Button button = new Button(parent, SWT.PUSH);
```

Customizing GUI components is significant in creating tailored user interfaces because it allows developers to create interfaces that match the specific needs and preferences of their users. For example, a customized button might be easier for users to click on, a customized text field might provide better feedback to the user, and a customized window might provide a more intuitive layout for the user.
