Create a Mac OS app to help mount network shares

I'm looking to create a MacOS app that will help mount 2 static network drives shares as well as multiple network shares based on the contents of a text file located in a public network share. We have a Windows vbs script that does this and I’m looking to create something for our Apple users to do the same. The interface is a simple Username and password with ‘Connect’ and ‘Disconnect’ buttons as well as a 3rd button that directs users to a help request form website. There is a third field that is just a drop down list of 2 different domain sites that needs to be appended to the username in order to connect. When I Command-K and manually mount a network drive, MacOS asks for my username/password and when I connect to the share my user name would be Domain\Username. When the user enters their username and password, our Windows version goes out to a network folder and finds a matching text file named after the username that contains network share locations that each specific user has access to and then proceeds to mounts them. Please let me know if you have any questions !
