how to add a function to a button in a window

import maya.cmds

Animation_Range = 10

def Create_Cube(increment):

    Cube = cmds.polyCube()

    cmds.move(increment, x = True)

for x in range(1,101,10):   

    Create_Cube(x)

cube = cmds.polyCube()

for i in range(Animation_Range):

    cmds.currentTime( (i+1)*10, edit=True )

    cmds.setKeyframe(cube,v=i, at="translateX")

window = cmds.window( title="Long Name", iconName='Short Name', widthHeight=(200, 55) )

cmds.columnLayout( adjustableColumn=True )

cmds.button( label='Create Cube',command = "Create_Cube(10)"  )

cmds.button( label='Close', command=('cmds.deleteUI(\"' + window + '\", window=True)') )

cmds.setParent( '..' )

cmds.showWindow( window )

this piece of code allows you to add a function to a button in a window in maya and in this case the button says create cube so when you press the button the code linked to the button would run and therefore a cube would be created.
