And since you access entry within runit you need to store it as a 
class variable, hence use self.entry

You need to bind self.runit. Otherwise Python is looking for a function
in the global namespace called runit...

As a method this must have a patrameter referencing the class instance
first, thus you need:

          def runit(self, event):

>             text = entry.get()

And since entry is a class variable(see above) you need to access it as
self.entry

>             command = "%s &" % text
>             system(command)

Personally I'd probably just do:

             system(self.entry.get() + ' &')

and miss out the other stuff.
However if you might start adding arguments to the command then your 
approach is better...

> NameError: global name 'runit' is not defined

Thats the lack of self in front of the runit refeence.
But you need to fix the other bits too...
