Creating an app with wall like facebook

i want to create an app which allows me to:

  • create an posts, making comments.
  • displaying posts on wall like on facebook or on forum(depends what's easier to create)
  • can temporarly set post as "reserved" or "available"
  • save current addres taken from location sensor.

I'll be very glad for tutorials and Your help!


What have you tried?

I haven't tried anything yet. all I have is an idea for a functional application and im looking for tutorials and examples to know how to do the app in practice.
