As @Roland points out, you can also assign a listener to each node. When doing so you can use a single callback method with this approach (mouse-pressed handler as example, but works with others too):

Assigning the handler to the nodes. Let's assume you have an array of buttons:

for (Button button : buttons) {
    button.setOnMousePressed(this::onPress);
}

Mouse pressed handler method:

void onPress(MouseEvent event) {
    int column = GridPane.getColumnIndex((Node) event.getSource());
    int row = GridPane.getRowIndex((Node) event.getSource());
    System.out.println(String.format("Node clicked at: column=%d, row=%d", column, row));
}
