Controlling GRC parameters with QT Creater

Dear GNU Radio Community, 

I'm working on a project to control a USRP channel frequency from QT creater GUI application, is it possible to implement a communication between QT and GRC using xmlrpm or tcp block etc to control the GRC parameters in real-time on the same computer in window.

Kindly help me to achieve this communication.
