I have an windows app and I want to send click event on it's window.
for example in android and using ADB.exe I use this code:
adb.exe shell input x,y
The answer to this question heavily depends on how the term "programming" is defined.
In any case, you can simulate mouse input in Windows using various utilities available for download online, or alternatively using PowerShell. Both of these approaches could count as programming.
It should be fairly obvious that the only way of simulating mouse input without using anything that counts as programming would be using a mouse.
