Use a GridLayout. You can change which Layout Manager netbeans is using by right clicking on the form, I think. Your GridLayout should use 1 row and 1 column, that way the buttons will be displayed vertically. Then just use the palette to add 4 buttons. Netbeans will automatically arrange them vertically if you use GridLayout like I just mentioned. To pop up a message with JOptionPane you can do

JOptionPane.showMessageDialog(null, "Message!");

To detect when one of your buttons was clicked, look at this tutorial. It is literally a matter of right clicking the button.
