My Huawei IDEOS phone is a basic Android, but it does everything I need. 

However, it has one huge flaw, screen is too tiny for my sausage fingers. I'd like to make the icons and text bigger on the home page and the app launcher. Is this kind of customisation possible without digging down into the OS roots. Where's a good place with information about getting started with customising my phone?

Google may have the answers to this, but I don't know my way around Android jargon well enough to compose a useful search.
