This should get you rolling:

from java.awt import Frame, Button, Label
from java.awt import Panel, BorderLayout

def closeit(e):
  f.dispose()

def doit(e):
  print "doit called"

b1 = Button("Left Butt", actionPerformed=doit)
b2 = Button("Right Butt", actionPerformed=doit)
p = Panel()
p.setLayout(BorderLayout())
pl = Panel()      # put buttons in their own Panels to keep
pr = Panel()      # their size 'natural'
pl.add(b1)
pr.add(b2)
pb = Panel()
pb.setLayout(BorderLayout())
pb.add("East",pr)
pb.add("West",pl)

p.add("Center",Label("This is label",Label.CENTER))
p.add("South",pb)
f=Frame("example", windowClosing=closeit)
f.resize(300,300)
f.add(p)
f.show()
