In your case it might be easier to just use a StaticPopupDialog, you can reference StaticPopup.lua for more detailed examples

local someVar
 
-- /run StaticPopup_Show("TestPopup")
StaticPopupDialogs.TestPopup = {
    text = "Some text",
    button1 = OKAY,
    OnAccept = function(self)
        someVar = self.editBox:GetText()
        print(someVar)
    end,
    hasEditBox = 1,
}

There is also the AceConfig input option if you want more full fledged options

The "Okay" button there is part of the DialogBox frame template

Here is an ugly example using the global variables because apparently I didn't bother making them accessible as keys at that time

local someVar
 
KethoEditBoxButton:HookScript("OnClick", function(self)
    someVar = KethoEditBoxEditBox:GetText()
    print(someVar)
end)
