I am looking for any project or example about a GUI which interface the values of imu to pc reader on python or C#

Do you have Arduino code that sends the imu data from the Arduino to the PC?

If not, start with that and test with serial monitor.
Next you can develop the PC side of things.

Robin’s updated Serial Input Basics might give you some ideas. Though it’s written for reception by Arduino, the principles can be used everywhere. You can e.g. send <x,y,z> from Arduino and parse it at the PC side.
