If you want to do something like this today I suggest making a list of 
the component names that you can then do an operation on. For 
example...

group = ['btnOne', 'btnTwo', 'fldOne', 'someList']
for c in group:
     self.components[c].visible = False

...could be used to make all the components in the "group" hidden. 
Rather than string names you could just as easily use the actual 
component references, it just depends on what you prefer. If you want 
to make this more generic then use setattr within a function that takes 
the group list, attribute name, and value as parameters.

def groupChange(self, group, attribute, value):
     for name in group:
         setattr(self.components[name], attribute, value)

attribute is a string like 'visible'.
