My problem is that at the moment I am making a GUI for a game and this GUI has many buttons. I had a problem earlier in my code where the actionListener I was using was looking for events in two buttons in rapid succession, not giving enough time for the second button to perform and action and rendering it useless. I thought I overcame that by making the second button a different actionListener in an inner class
button5.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
and now I'm trying to do the same for a third (and eventually fourth and fifth button
P1Roll.addActionListener(new ActionListener(){
public void ActionPerformed(ActionEvent e){
but it is throwing me all kinds of errors. As I am very new to swing, I am unsure how to proceed. Any tips on this, or anything in my code at all would be very much appreciated. :)

From an initial reading of the code, it appears you're creating the anonymous ActionListener with incorrect syntax.
P1Roll.addActionListener(new ActionListener(){ public void ActionPerformed(ActionEvent e){
}
@Override
public void actionPerformed(ActionEvent e) {
int turnNum;
for(turnNum; numTurns > 0 ; numTurns -- ){
}
}});
Should be
P1Roll.addActionListener(new ActionListener(){ public void actionPerformed(ActionEvent e)
{
int turnNum;
for(turnNum; numTurns > 0 ; numTurns -- )
{
}
});
