There are so many but I'd do webpages!!!
You need no software except notepad which is on EVERY windows computer
You need to learn HTML (body, mainframe).

After that CSS (style, color, format).

Then Javascript (clicking, interactivity).

Coding is really fun and after you learn the basics, it come naturally. You can make these files in notepad and when you save, you change the save type from txt to *. Then you save it as "webpage.html" and you can open it in internet explorer or anything. For example copy and paste this to start
First PageHello world, this is my first webpage
paste into notepad and when you click save, where it says "Save as type: Text Documents *.txt"
click it and change it to "All Files" and then in the box type in "page.html" and save it onto your desktop, then double-click it and it should open up a webpage that says "Hello world, this is my first webpage"
