Welcome to web programming 101! We were all newbies once. There are several components to an application like this, but to get you started, what you are describing is very similar to the Guestbook demo application included in the SDK. Look in your demos/guestbook folder in your python appengine SDK folder, and you will see the simplest possible example of posting a form, storing the data, and displaying it back on the page. Open the guestbook.py file to get an idea of how it all works.
Here's the basic idea: when you load the main page (the root http://appname.appspot.com/) the application is directed to the MainPage class (see the application = lines near the bottom of the file). This class, in its get method, query's the BigTable for the last 10 greetings, loops through them, and writes them to the response. Then, at the bottom, it writes the form to the response. You could always switch this up and write the form first and then the Greetings, or split them up to separate pages, or anything along those lines. Notice that the form's action points to the /sign url, which the application (at the bottom) routes to the Guestbook class. It's post method creates a new Greeting record, sets its author and content data (the date is automatically set when it is saved), and saves the Greeting to the BigTable. Finally, it redirects you back to the root / to display the Greeting you just added (and up to 9 others) and the form again. This tutorial describes the application in more detail: http://code.google.com/appengine/docs/python/gettingstarted/ Take a look at the tutorial and source code, and let us know if you have any more questions.
