Java SWT: syncExec and asyncExec packaging for code cleaning

I have a Java application using SWT as a toolkit and am tired of all the ugly code table code needed to update a GUI element.

Just to set the disabled button to enable, I need to go through something like this:

shell.getDisplay().asyncExec(new Runnable() {
    public void run() {
        buttonOk.setEnabled(true);
    }
});

I prefer my source code to be as flat as possible, but I need a whopping 3 levels of indentation to make something simple.

Is there any way to wrap it? I need a class like:

public class UIUpdater {
    public static void updateUI(Shell shell, *function_ptr*) {
        shell.getDisplay().asyncExec(new Runnable() {
           public void run() {
              //Execute function_ptr
           }
        });
    }
}

And you can use it like this:

UIUpdater.updateUI(shell, buttonOk.setEnabled(true));

Something like this would be great in order to hide this terrible mess, which apparently seems to need to be done.
