Queue Management System Rendering Fonts and Texts

I need to create an app or script running on Raspbian free in the future to use it on other linux operating systems. The app is a Queue Management System that works in this way: 1) at the start it show the number 00 2) right arrowkey: grow the number of one step, so for exampe ->1 -> 2 -> etc.. till 99 3) CONFIGURATION FILE: - permit the option to show a letter before the number, so for example then the counter would looks like this: P01,P02 etc... - define the file name name of the true type font font to use (all the used fonts are stored in the same folder) - position of the text in pixel: X-Y - color of the text - dimension of the text - define the filename of the .png file(24+8 alpha) 32 bit that will works as a mask in foreground - give a unique id to the QMS - Every Queue Management System has 3 options: option 1) only show the QMS managed from the arrow keys option 2) don't show any text produced form the arrow keys and only listen the ssh to receive informations to show one ore more QMS on the same display, on the same layer option 3) show the QMS managed from the arrow keys plus send the configuration and the number to show to one or more devices in the LAN trough ssh. notes: I use Raspberry Pi Model 3B and B+ with Raspbian
