Newbie PHP insatllation questions

I'm new to PHP. An experienced IT professional, albeit in the Windows
environment, but this is uncharted territory. Please bear with me,
paricularly if I've missed answers in the archives. I also find the install
notes with the PHP file distribution complicated.

 

My core question is this. How do I get a working PHP (and SQLite)
environment on a Windows 7 PC? I'm building a bookseller website which will
have the book inventory stored as an SQLite database, produced by AbeBooks'
Homebase 3.0 product. I want to develop and test this locally, then move it
to the hosting ISP's server.

 

Can anybody provide a step-by-step set of instructions to make this
development environment happen?

 

Many thanks,
