Creating a Bluetooth COM Port on Windows Programmatically

I have developed a Qt application that communicates with a specific bluetooth device. The application works on linux, android and mac flawlessly, but the qbluetooth api is not supported on windows. I have selected the serial api as a workaround, and have successfully done the task using a virtual COM port on the bluetooth device. The problem is that I don't want the end-user to create the COM port, and want to create it in setup time programmatically. I have done an extensive search, but have found no clue on it. Can anyone give me a hint on it? Thanks in advance.
