I know, Python is not C++, but I wanted some exercise in this language.
The specified font size and the area locations do not fit too well, even
if the font size would be scaled down by around 75%. Therefore I have used \resizebox to force the text to the size of the specified area location.
The word is placed via \put of the picture environment. There are more
powerful environments for drawings like TikZ or pstricks. But advanced features are not needed here and picture is much more efficient and faster.
The coordinates are transformed, since the vertical axis has the opposite
direction of the y values need for the picture environment. The program
calculates the minimum and maximum values and sets the lower left corner
as new origin.
Before the word is set, the program sets some lines to show the specified
rectangle.
The Python program can be called with the text file name as argument. Without argument, the text data are taken from the standard input. Output is standard output, which can be redirected to a TeX file.
The font and size settings are optimized, thus that the font is only defined
once. Also the font is only set for a word, if the font has changed.
The generated file is processed with LuaLaTeX or XeLaTeX because of package fontspec. Then it is easier to use arbitrary font names, as long as LuaTeX or XeTeX know, where to find them.
Some characters need special treatment in TeX, see the program code for an example, how to deal with these characters.
A little more elegant would be to put the TeX preamble into a new LaTeX class
file. Then the generated TeX file would just contain \documentclass{...} as whole preamble.
