What might help you accomplish this is to refactor the code into a class,
so that you can start saving a bunch of the state. You create all the
widgets, and the data structures to set things up, but your callbacks would
either need to be wrapped up with closures to the references, or, would
access them simply off the state of the instance:
So you can track your current degree values as they are updated, via:
self.curMoveDegVal = []
And I would suggest refactoring the block of code that updates your current
text values, into a method that will do them using those instance
attribute. Then its just a matter of tacking on a little more to your
Accept button callback:
...
applyButton = cmds.button(
l='Apply',
height=26,
c=self.degToRad)
...
def updateText():
# update the current degree text with
# self.curMoveDegVal
# self.curScaleVal
def clickCmd(self, *args):
self.degToRad()
self.updateText()
def degToRad(self):
xDeg = self.xDeg
yDeg = self.yDeg
zDeg = self.zDeg
relativeOpt = self.relativeOpt
applyFor = self.applyFor
...

I'm not saying this is *the* way to do it, but this works, by breaking it
up into a two step formatting:
vals = [.1, .23456, 12.23]
print 'Move: {0:>10} {1:>10} {2:>10}'.format(*map('{0:0>7.3f}'.format,
vals))
First it converts the float to 3-precision, and left padded with zeros
Then it just does the right alignment to the strings.

That's some really clean looking python in my opinion!
I wouldn't say "always write a class", but in your case you would probably
want to explore writing one since you already have the need to store state,
like references to your widgets, and your data structures, for use in
callbacks.
