Would it end up being a 30-90mm lens when its on the GH2?
GH2 What would be the focal length be of Zeiss Zoom LWZ.2 15-45mm with MFT mount?

Nope it would still be a focal length of 15-45. BUT, its field of view equivalent would be a 30-90mm lens.

mounting it on the GH2 does't change the value of the focal length, it changes the angle of the view.
The long answer you will the equivalent to a 28-86.2mm from a full frame still camera and a 16.7-50.1mm from a 35mm movie camera.
See that the values of "equivalent" you mentioned are for still pictures only (and 5DmkII) which are so far away form the values of hollywoodian film cameras.

Phenix, can we clarify this? My numbers arent precise - but precise would be 30.1mm How are you getting 28?

I believe that he is referring to the video crop of the sensor which is closer to a 1.8 factor.
