when i made labels/buttons, i used the setImage to do it ex: setImage(new GreenfootImage("String " + minerals, 20, Color.GREEN, Color.BLUE)); where "String" is the string you want displayed, the + variable will display a variable (adding it to a string), the 20 is the font size (change to whatever size you want), the first color (green in this example) is the color of the text, and the second color (blue in this example) is the color of the background of the box created. this site has a list of the colors you can use for it: http://www.geom.uiuc.edu/~daeron/docs/apidocs/java.awt.Color.html (just make sure you make them uppercase like in the example)

'minerals' is an int field name that darkmist002 has in his class, not necessarily something you should put in your code. Your class code should be more like the following: 
import greenfoot.*;
import java.awt.Color;

public class Label extends Actor
{
    public Label(String text)
    {
        // create the text image
        int fontsize = 20; // change as desired
        Color fontColor = Color.BLACK; // change as desired
        Color bgColor = new Color(0, 0, 0, 0); // transparent background
        GreenfootImage txtImg = new GreenfootImage(text, fontsize, fontColor, bgColor);
        // create the base image
        GreenfootImage img = new GreenfootImage(text.getWidth()+20, text,getHeight()+10);
        bgColor = Color.YELLOW; // change as desired
        img.setColor(bgColor);
        img.fill();
        // draw text image on base image
        img.drawImage(txtImg, 10, 5);
        setImage(img);
    }
    
    public void act() 
    {
    }    
}

There would be a lot more involved if you actually wanted to change the font style as well (importing the Font class and applying the font style to an image before drawing a string on it).
