SPE is likely going to be your best lower effort approach. The book provides several examples for creating Context Menu options and prompting for input.
New-Item allows for the creation of items at a path using the specified template.
Copy-Item will be the go-to command for copying items. Call it for each destination. Perhaps not needed if you are only concerned with new items.
One option for input is to use
Show-Input to request a value from the user.
Read-Variable is another option if you want a more sophisticated dialog for users, especially when more knobs and levers are required.
Show-Input "Please provide 5 characters at most" -MaxLength 5
I recommend you explore the book for a few minutes then let your imagination run wild.
If this is your first time using SPE then start in the PowerShell ISE and run some simple commands. You can save the script in the Script Library and later add it to the Content Editor integration. The book walks you through just about everything you need to get this working.
The Slack channel #module-spe is another good resource for discussion.
