Only beside. But how can I then take care that the text are displayed into the empty-scene. I think you need overlay or something for that.
Every image function returns an image, so you can use beside to create an image of your text with the cursor in the right spot, and then place that image in your empty scene however you want (you used place-image, which would work, but I would suggest place-image/align). In general, I would suggest (as HtDP does) that you experiment with each piece of the image in the interactions pane, and then experiment with composing them until you get what you want. For instance, use the interactions pane to try to get the text and cursor together using different image functions until you like what you get, then do the same with composing that result and the background.
