Creating Sencha Ext JS App Prologue

Going to Ext JS is like diving into a very deep ocean where you only have flippers. But don't worry, you will not be alone. I will be accompanying you through the whole process. And I don't want to warn your regarding Ext JS because this is a fun stuff to learn.
