Swing gets its fonts via UIManager. Override the default values and then
follow the procedure for changing the Look And Feel.

Something like this may work:
import java.awt.Font;
import java.awt.Frame;
import java.awt.Window;
import javax.swing.SwingUtilities;
import javax.swing.UIManager;
public class SwingFontManager {
public static void changeDefaultFont(Font font) {
UIManager.put("Button.font",font);
UIManager.put("ToggleButton.font",font);
UIManager.put("RadioButton.font",font);
UIManager.put("CheckBox.font",font);
UIManager.put("ColorChooser.font",font);
UIManager.put("ComboBox.font",font);
UIManager.put("Label.font",font);
UIManager.put("List.font",font);
UIManager.put("MenuBar.font",font);
UIManager.put("MenuItem.font",font);
UIManager.put("RadioButtonMenuItem.font",font);
UIManager.put("CheckBoxMenuItem.font",font);
UIManager.put("Menu.font",font);
UIManager.put("PopupMenu.font",font);
UIManager.put("OptionPane.font",font);
UIManager.put("Panel.font",font);
UIManager.put("ProgressBar.font",font);
UIManager.put("ScrollPane.font",font);
UIManager.put("Viewport.font",font);
UIManager.put("TabbedPane.font",font);
UIManager.put("Table.font",font);
UIManager.put("TableHeader.font",font);
UIManager.put("TextField.font",font);
UIManager.put("PasswordField.font",font);
UIManager.put("TextArea.font",font);
UIManager.put("TextPane.font",font);
UIManager.put("EditorPane.font",font);
UIManager.put("TitledBorder.font",font);
UIManager.put("ToolBar.font",font);
UIManager.put("ToolTip.font",font);
UIManager.put("Tree.font",font);
Frame[] frames = Frame.getFrames();
for (int i = 0; i < frames.length; i++) {
SwingUtilities.updateComponentTreeUI(frames[i]);
// the following could be recursive
Window[] windows = frames[i].getOwnedWindows();
for (int j = 0; j < windows.length; j++) {
SwingUtilities.updateComponentTreeUI(windows[j]);
}
}
}
}
