Guidelines for injecting Swing components using Guice?

I am working on a Java Swing application with Google Guice as an IOC container. I directly insert components, but this allows Guice to create a component outside of EDT.

The application looks something like this:

private Panel1 panel1;
private Panel2 panel2;

@Inject
public class Application(Panel1 panel1, Panel2 panel2) {
    this.panel1 = panel1;
    this.panel2 = panel2;
}

Considering the issues here and here , I came to the conclusion that the loader was introduced instead of the component itself.

private PanelLoader1 loader1;
private PanelLoader2 loader2;

private Panel1 panel1;
private Panel2 panel2;

@Inject
public class Application(PanelLoader1 loader1, PanelLoader2 loader2) {
    this.loader1 = loader1;
    this.loader2 = loader2;

    loader1.load();
    loader2.load();

    this.panel1 = loader1.get();
    this.panel2 = loader2.get();
}

public class PanelLoader {
    private Panel panel;
    public void load() {
        SwingUtilities.invokeLater(new Runnable() {

            @Override
            public void run() {
                panel = new Panel();
            }
        });
    }
    public Panel get() {
        return panel;
    }
}

It is right? Is there any best practice for this?
