I am working on a novel and it has become necessary for me to find a SME (subject matter expert) on some technical computer things like creating popups.
Any takers? I promise to thank you in the acknowledgements should the book ever be published.
Are you sure people who know how to create those annoying things would want to admit their shame? 
Can you be more explicit?
You might ask the mods if you could start a running GQ thread wherein you post technical questions as you have them (and then thank the SDMB community).
BigT - you make an excellent point. 
What do you need to know? The “traditional” pop-up, that is one that pops up in an entirely new window has fallen out of fashion due to ubiquitous pop-up blocking software and extensions in favor of JavaScript-based “hover” pop-ups, which are much harder to block (you have to disable JavaScript, which means also disabling much of a website’s functionality).
There’s a pretty technical audience here. If you just post your specific questions, I’m sure you’ll get good answers.
