Is there any way to show our custom message in Qgis Status bar using python? Just like in arcgis IApplication.statusbar.message(0) = "Please wait..."
like that is there any option to show progressbar in Qgis like IApplication.progressbar.show()

StatusBar
There is iface.mainWindow().statusBar() which returns a QStatusBar
iface.mainWindow().statusBar().showMessage( u"Hello World" )
MessageBar
Starting from QGIS 2.0 there is also QgsMessageBar which is able to display unobtrusive messages
iface.messageBar().pushInfo(u'My Plugin says', u'Hey there')
Advanced
The message bar can also show any QWidget (like a QProgressBar) with a close button and a timeout (5 seconds in the example).
from PyQt4.QtGui import QProgressBar
from qgis.gui import QgsMessageBar
msgBar = iface.messageBar()
pb = QProgressBar( msgBar )
msgBar.pushWidget( pb, QgsMessageBar.INFO, 5 )
msg = msgBar.createMessage( u'Hello World' )
msgBar.pushWidget( msg, QgsMessageBar.WARNING, 5 )
More info about QgsMessageBar can be found in this answer by NathanW How to address the new "Task-Completed" QgsMessageBar in Python? Thanks for pointing out Curlew

In the python console for QGIS < 1.9 it would be:
qgis.utils.iface.mainWindow().statusBar().showMessage( u"Hello World" )

In the QgsMessageBar you're able to display any kind of widget. I would not know that this is possible in the status bar. Commented Apr 22, 2013 at 11:36

I am very new to qgis and python.. could you please give me example for QgsMessageBar? and what is the meaning of using 'u' prefix in "Hello world"– venkatCommented Apr 22, 2013 at 11:40

The u prefix is for unicode strings. It will also work without this. For the QgsMessageBar you have to get the current development version of QGIS or wait for the release of 2.0. Commented Apr 22, 2013 at 11:47
