Can it be done (by me)?

[alexanderzid]

So, here's the deal;
There is a demand for an app, and noone associated with the demand seems to be able/ willing/ have time to do it.
I am an absolute beginner to both programming and C#, but I thought "if noone else is making it, why cant I use it as my learning project".

So, firstly, what I want to make is:
An app extracting the information from a given website by the use of XML. The associated XML will be made by the websites owner.
I want the information (which are LARP events) to be available to the app to enable a few possible options:
- Get a notification when a new event is posted
- Mark events of interest
- Get a notification when a marked events dates are coming up (last date for applying, paying, etc.)
- The ability to fill out and send a given form (already existing on the website)

Then, secondly, can it be done by me?
I have lots of spare time, but currently no experience with programming. There is no rush in getting this app up and available, but if it would take _me_ years to make, it probably wouldnt do much good.

So, what I am really asking is this:
For an absolute beginner, how long would it take to be able to make the above- mentioned app (in C# using Visual Studio)?
How much of the functionality exists freely available for copying from other developers?
Could I do it (within a reasonable period of time)?

What kind of app are you looking for? A desktop app? A web application?

Right, I should have specified that.
Android/iOS/Win10 application.
