Select which software to install via Dialog

I would like to select various software to install on my Linux Mint system via a bash script. I would like to use dailog --checklist because it shows a simple GUI that newbies can use. I can get the GUI to show the selection, but I do not know how to install the selected items. Below is an example of some software to install.

#!/bin/bash

dialog --checklist "Select needed software" 20 75 5 \
"Evince" "PDF Viewer" on \
"Pinta" "MS-Paint like Software " off \
"htop" "Shows running processes" off \
"vim" "txt editor" off

Thank you for your time and help.
