How about WiseScript/SMS Installer. I believe that you can download SMS Installer free from the Microsoft web site, they (the Wise and MS versions) are basically the same program.
All the commands available are listed on the left hand side, syntax errors are nearly impossible, no need to setup variables (altho you can), but IF/ELSE statements and while loops are available. Select your command from the list on the left hand side, a fill in pop up box appears for you to complete the details and you're done. Eg. select the "Delete file" command, box appears, type in name inc path of file to delete, check or uncheck the 2 options: 1. Include sub directories 2. Remove the directory containing the file. VERY EASY!! Even easier when you see it in action.
You can compile to an exe and it is not limited to installations. It is actually quite flexible and when you get more advanced, you can learn about custom actions to add functionality eg. Calling DLL functions.
I use it as a quick and easy way to get things done. It should give your mom confidence without jumping in at the deep end. At the same time, she should be able to achieve useful results.
