See e626 Setting the Stretchyness of Rows and Columns in a GridBagLayout Using Layout Weights for an explanation of stretchyness and weights. This example demonstrates how to set the weight of a row or column by assigning the weight on a component. 
See e622 Creating a GridBagLayout for an example on how to use a gridbag layout with gridbag constraints. 

    GridBagLayout gbl = new GridBagLayout();
    container.setLayout(gbl);
    
    // Place a component at (0,1) with a column weight 1 and
    // a row weight of 2
    GridBagConstraints gbc = new GridBagConstraints();
    gbc.gridx = 0;
    gbc.gridy = 1;
    gbc.weightx = 1;
    gbc.weighty = 2;
    gbl.setConstraints(component, gbc);
    container.add(component);
