Creating a Twitter app without a mobile (or mobile network unsupported)


Hi, I am a rare beast … I do not have a mobile phone! So I cannot create a Twitter app or so it seems. I tried to register my daughter’s mobile # (UK Vodaphone) on my Twitter a/c so that I could hopefully go on to create the app that I want. My daughter received a text message with a code but every time I entered the code, I received a message saying that another code had been texted. Tried entering that code but same thing again. I kept trying but just got more codes and got nowhere. I want to create an app that will enable my Twitter posts to appear on my website. What can I do please?
