Getting started with app engine in windows

First thing you need to do is download Aptana studio for windows from http://www.aptana.com/products/studio3/download . Its only because aptana studio is a very good IDE for python stuffs. I personally prefer Aptana studio over other IDEs for app engine stuffs. Its pretty easy to write applications and deploy them to the app Engine Server.
Once Aptana is studio is downloaded install it and open it. Now change the perspective to PyDev. You can do this from Window->Open Perspective->Other. Now select PyDev and it should be done. The next step is to set the interpreter. To do this goto Window->Preferences. A dialog box will pop up. In the dialog box goto PyDev->Interpreter Python.  Now Click on New, another dialog box will pop up. Now browser the executable file of python. For me, its C:\Python27\python.exe. Click OK.  Again an OK.And one last OK. In a few minutes the IDE will be ready for use.

Now its time to setup the app engine sdk. Download the app engine sdk from  https://developers.google.com/appengine/downloads .Its about 33 MB of file and should not take long to download. Once its downloaded run the file. Click Next.

Accept the terms in the license agreement and click Next.

Choose your installation directory and click Next. 

And then click on install. The installation will take a few minutes. Be sure to click on Yes if the UAC pop ups. 

Finally we are done, we can start writing our google app engine.
