The tutorial might be a little outdated.
Have a look at the source code of the "GoIn" game made with the litiEngine.
I think that you can find what you want in the "Program.java":
Basically, you create an "ImageComponent" containing the size, the position and the text that you want.
Then, you can add it to a "Screen" with: ".getComponents().add(yourImageComponent);".
I don't know for the font, though. Maybe in the "GuiProperties"...?
