Simple solution. Got windows? Good! Got a paint program that can make pngs? Good! Got 0 programming knowlege? That's Ok!
Download the corona sdk from www.anscamobile.com
Then download Notepad++ (Google is your best friend)
Finally, find some tutorials on the "Lua" programming language, so you can use it in co-operation with the Corona SDK! (Free but you have to handle distribution yourself, you can put it on the Android market or whatever if you pay though)
Remember, never give up, proven study says you'll probably make your first angry birds clone in 1 day!
Also, you can get knowlege by looking at open source games made with Corona!
First, do you know how to program in Java? If not, you must learn how to program in Java first (for the most part, all applications for Android are written in pure Java). Next, you must install and setup the Android SDK (the instructions for how to do this are on the official website).
Eclipse is, as far as I know, the only officially supported development environment for Android. You might look in to Unity, but I don't think that will be of much help if you do not have content of your own or serious programming skills (you don't mention whether or not you do):
