如何通过MigLayout进行中间对齐

Question

I am creating a desktop application using swing and miglayout. How would I get the below gui? C1 being component 1.

+-----+ +-----+
| C1  | | C2  |
+-----+ +-----+ +----+
+-----+ +-----+ | C4 | 
| C3  | | C4  | +----+
+-----+ +-----+

Thank you.

Update with regards to the below answer.

Code is:

panel = new JPanel();

    MigLayout layout = new MigLayout("debug", "[][][]");
    panel.setLayout(layout);

    JCheckBox reptJCheckBox = new JCheckBox("REPT");
    JCheckBox tstcJCheckBox = new JCheckBox("TSTC");
    JCheckBox devJCheckBox = new JCheckBox("DEV");
    JCheckBox tstyCheckBox = new JCheckBox("TSTY");


    JButton openButton = new JButton("Open");

    panel.add(reptJCheckBox);
    panel.add(tstcJCheckBox, "wrap");
    panel.add(tstyCheckBox);
    panel.add(devJCheckBox);
    panel.add(openButton, "spany 2, wrap");

Note that you can't add the same component twice in a container, so having C1 and C2 tiwce is a mistake.

About components layout, I think the question is how to vertically center C3 component. Well this is the default behavior when you span rows using spany constraint: component gets vertically centered. Just try this snippet:

    MigLayout layout = new MigLayout("debug, fill", "[][][]");

    JPanel panel = new JPanel(layout);
    panel.add(new JButton("Button"));
    panel.add(new JButton("Button"));
    panel.add(new JButton("Button"), "spany 2, wrap");
    panel.add(new JButton("Button"));
    panel.add(new JButton("Button"));
