WebSphere MQ Explorer requires root access

WebSphere MQ Explorer is my favorite tool as its ease of use compared to command line. This tool is a separate installation apart from the MQv8 installation, the component name would have this file name pattern MQSeriesExplorer_<suffix>-8.0.0-2.x86_64.rpm. Unfortunately, it requires root user which has mqm group granted in order to create a queue. Otherwise a prompt showing following error stopping me to proceed further.

****************************************
* Command: /opt/mqm/bin/crtmqm  Q1
****************************************
Access not permitted. You are not authorized to perform this operation. (AMQ4036)

Since this tool is installed in Ubuntu 14.04, and it was launched in Unity Launcher. Unlike command prompt, sudo would be my best friend handling root access control. Unfortunately, this is a graphical environment, I would need graphical sudo to help me. Here is the clue, open this file: /usr/share/applications/IBM_WebSphere_MQ_Explorer-Installation1.desktop (this file requires root access as well), and modify the line:

...
Exec=/opt/mqm/bin/MQExplorer
...

with this:

...
Exec=gksudo -k -u root /opt/mqm/bin/MQExplorer
...
