Hello!
I am a bit lost and really need help and/or advice going forward.
I am trying to help a friend who was diagnosed with locked-in-syndrom.
While almost completely paralyzed, he is fully aware and able to move his thumb slightly which is why I would like to establish morse communication!
Through the great Arduino community, I was able to build a morse module (with a touch sensor) and, using Vladimir Krsmanovic' sketch, the program recognizes the morse patterns and writes the corresponding letter into the serial monitor.
Now I need to ditch the serial monitor-approach (since it's not practical enough) and provide him with a proper windows program which displays the morse alphabet on the left and the Arduinos input on the right-hand side.
This would enable him to see the morse-alphabet, put in the needed combination of code and see the corresponding letter simultaneously appear on the right-hand side of the display.
He needs the program to be able to practise and train his muscles.
In time the error rate will go down and we can move onto scrolling devices and the like but for now we'd need something like this:
The program would differentiate short and long pauses between signals, either starting a new letter or a new word.
Essentially I need almost exactly what Vladimir Krsmanovic' sketch is already doing but I need it displayed in a graphic interface!
(However I don't need the program controlling the arduino!)
How do I do this?
Which language should I use?
How do I make the program use the USB-port for input?
How to I make the program talk to the Arduino?
Can you point me to anything similar?
Thank you for taking the time to read this!
Any knowledge that could help is very much appreciated!

This is the aforementioned adapted sketch I've been using:

const int buzzer = 12;
int ledState = HIGH;
int TouchSensorState = LOW;
int lastTouchSensorState = LOW;
int doesitwork = LOW; // variable used for debuging early versions of the code
int pause_value = 250; // depending on your skill and how fast your fingers are you can change this value to make typing a message faster or slower
long signal_length = 0;
long pause = 0;
String morse = "";
String dash = "-";
String dot = "*";
boolean cheker = false;
boolean linecheker = false;

long debounceDelay = 50;

{
++signal_length;
if (signal_length<2*pause_value) //this help to notice that there is a change in the signal length aka that its not a dot anymore but a dash
{ // best use for the measuring of signal_length would be use of the millis() but this was used for simplicity
tone(buzzer, 400) ;
}

}
}
