What are your objectives in learning webpages? Is this for your personal use only or are you looking to develop a skill to use at work? Myself, I use notepad++ as I prefer to manually create pages. I used an older version of frontpage years ago. The color picker was excellent as I recall. Think about what tool that your wife uses. What does she or doesn't she like about her software?
Some businesses will dictate what software is used for creating pages. Dreamweaver seems to be a popular tool. Try googling for webpage creation software. You might have to test drive a few before you find one that you like.http://www.w3schools.com/default.asp
