Here is an example of a basic calculator for Python S60:

import appuifw
 
z=1
c=0
x=float(appuifw.query(u"Type a number:", "text"))
while(z!=2):
     operation=appuifw.popup_menu([u"+", u"-", u"*", u"/"])
     y=float(appuifw.query(u"Type a number:", "text"))
     if(operation==0):
		rez=x+y
     if(operation==1):
		rez=x-y
     if(operation==2):
		rez=x*y
     if(operation==3):
		rez=x/y		
     x=rez
     continueoption=appuifw.popup_menu([u"%f" % (rez), u"Quit"])
     if(continueoption==1):z=2

Here is the more complex version, which provides more functionality:

from __future__ import division
from math import sin,cos,tan,sqrt,log
import appuifw
import e32
 
def lg(x,y):
	ex=0
	while(pow(x,ex)<y):ex=ex+0.01
	return ex
def quit():
	app_lock.signal()

#Operations is for doing classic mathematical calculations
#Basic is for simple operations while Scientific provides more complex functions
#Trigonometry is for calculating functions like sin, cos, tg etc.
