I have tried in contextMenuEvent method but that gives me on right click :/
What am i missing ? Any help will be appreciated.

It works in Linux but not in windows.
Below is code I used for systemtrayicon with left click support in windows. This might work for you as well.
QtCore.QObject.connect(self, QtCore.SIGNAL("activated(QSystemTrayIcon::ActivationReason)"), self.iconActivated)
def iconActivated(self, reason):
if reason == QtGui.QSystemTrayIcon.Trigger: // left click, right click is Context
self.contextMenu().activateWindow() // menu will disappear on clicking any where other than menu
self.contextMenu().popup(QtGui.QCursor.pos()) // display menu at cursor location

Looks like you could use the setMenu method:
#!/usr/bin/env python
#-*- coding:utf-8 -*-
from PyQt4 import QtCore, QtGui
class myWindow(QtGui.QWidget):
def __init__(self, parent=None):
super(myWindow, self).__init__(parent)
self.actionHello = QtGui.QAction(self)
self.actionHello.setText("Hello")
self.menu = QtGui.QMenu(self)
self.menu.addAction(self.actionHello)
self.buttonShow = QtGui.QPushButton(self)
self.buttonShow.setText("Button with menu")
self.buttonShow.setMenu(self.menu)
self.layout = QtGui.QVBoxLayout(self)
self.layout.addWidget(self.buttonShow)
if __name__ == "__main__":
import sys
app = QtGui.QApplication(sys.argv)
app.setApplicationName('myWindow')
main = myWindow()
main.show()
sys.exit(app.exec_())
