You can wait for the next version of calcE to come out.

check out Version 2.2 demos on Custom Ticks and Custom Axes*)
I have recently been working on this exact problem, but believe me it is not 
simple. 

I had to create the desired ticks as geometric objects, insert them in 
Epilog, and then leave dummy "blank" ticks of the proper length in FrameTicks 
to make sure that room was reserved for them. Even that is not the whole 
story. The way MMA handles Ticks and Frameticks is ugly as sin, and nobody 
would be happier than me to see it cleaned up. I could save about 40K of 
code.

In case you're listening, WRI:
Axes, Ticks, Frames and FrameTicks need to be handled as fundamental 
geometric objects, just like Polygons or Disks or anything else. Give the 
user complete control over the configuration and display of these objects.

Homework exercise: Try to display tick labels on the right side of a vertical 
axis, or above a horizontal axis. I can do it, and so will the next version 
of calcE. But I don't want to talk about it -- it's disgusting!
