Meaning that, if you want an action to be executed through a button, you 
have to create an operator first.

import bpy
class YourOperator(bpy.types.Operator):
	'''docstring'''
	__idname__ = "some.path.to.operator" # like "myops.resize"
	__label__ = "The string you see ie. in command search (ctrl+space)" # 
like "My Resize"

	__props__ = [] # list of props used, see release/io/export_ply.py for 
example

	def poll(self, context):
		# checks to ensure your operator has what it needs
		return True # or False if context is not correct, ie no selected objects

	def execute(self, context):
		# here your original resize() code
		return ('FINISHED', ) # or 'CANCELLED' or any of the others, depending 
on what you need


To ensure your own operator actually gets registered to the operator 
system, you have to do also:

bpy.ops.add(YourOperator)

Anyway, check export_ply.py and the pov render engine integration 
scripts for many cool examples of  what you can do to integrate your 
code tightly with Blender in a great way.
