The code below will help in creating transparent objects, texts and many more things in PyS60.

import appuifw

import e32
 
def quit():
    global running
    running = False
 
def handle_redraw(rect):
    canvas.clear(0x009900)

    textimgsize = (320, 20)
    textimg = graphics.Image.new(textimgsize, "L")
    textimg.clear(0x000000)
    colorimg = graphics.Image.new(textimgsize)
    colorimg.clear(0xFFFFFF)
 
    textmsg = u"75% transparent text"
    fontspec = (None, None, graphics.FONT_BOLD)
 
    tleft, ttop, tright, tbottom = textimg.measure_text(textmsg, fontspec)[0]
    tw = (tright - tleft)
    th = (tbottom - ttop)

    textimg.text((-tleft, -ttop), textmsg, alpha, fontspec)
    canvas.blit(colorimg, target = ((bw - tw) / 2, (bh - th) / 2), mask = textimg)
 
canvas = appuifw.Canvas()
appuifw.app.body = canvas
bw, bh = canvas.size
appuifw.app.exit_key_handler = quit
 
running = True
while running:
    handle_redraw(None)
    e32.ao_yield()
