GridLayout is a very simple layout manager that can arrange components in a grid of rows and columns. Every cell in the grid, and thus every component, is resized to be the same exact size.
GridBagLayout is much more complex, and much more flexible. It also arranges components in rows and columns, but individual components can span multiple rows or multiple columns and thus the components in the grid can vary in size.
