How to build an APP for tablets

Does anyone know the correct forum to submit a question about building an app for tablets?
If i'm in the right place, then this is my question:

I need to build an app to help me sort my files on a large tablet. I'm a beginner at app building so i need some really basic guidance.

I don't need the app to manipulate my current system files, i'm just looking for developing a system that helps me manage all my jobs into different categories such as :

1) preliminary review set
2) building review set
3) bid set
4) filing set
5) construction set

The idea is that when a job is at a certain stage of development it gets put into a certain category and this ultimately triggers an action in the form of an email such as : "need to bill the client for 30% of contract fee".
so basically i am dropping and dragging a job into a specific category.

Right now my system is this: a bunch of folders all over my office with post-its on them reminding me at what stage the job is at and so i know how much to bill the client.

The app I build can be either for iPad, Android or Windows but keep in mind i would like it to be on a large tablet, bigger than the current iPads size.

Thank you

Well, I think the first question is do you actually have any programming experience and, if so, in what languages?

In general...

For Apple tablets: you'll need to know Objective-C
For Android tablets: you'll need to know Java
For Windows tablets: you'll need to know either C++, C# or Visual Basic.Net

If the answer to the above question is something like, "no I have no programming experience" then I'm afraid the obvious answer is that you'll need to go and learn to code in at least one of these languages.
