I have been experimenting a little. Below the code I have. A lot has
to be changed. For example instead of hard-coded the number of lines
should be calculated, the text should come from an input file, an
error should be generated when the text is to wide, the font-size
should between certain values be dependent on the widest line, the
colours and parameters should be selectable, I should use a better
font, …

But I have something that works and I can build on. The output is
