My application is one of several front-ends to a shell-script based
installer. The back-end runs on multiple platforms and provides all of
the resources (strings) to the various front-ends upon request. It is
not feasible to restructure this application so that the Cocoa based
front-end uses resources from a NIB-file, they need to be provided by
the back-end at runtime.

Obviously you have to use bindings where titles of each of you controls need to be bound to a controller object which could be a kind of facade to your strings that come from your back-end.

If possible, I'd like to avoid having to manually query for each internationalized string in code. I'm a Cocoa newbie, so maybe there is something obvious that I'm missing, but it looks like unless I can pass an argument to a binding, I'm basically out of luck.

As I said, write a facade which hides all the details as how the title strings are generated. Have clean KVC compliant methods to return those titles. And in NIB bind your controls to appropriate keys governed by the KVC compliant methods. Read more on KVC-KVO :

However there would be a problem where localized strings may have different sizes in different languages and you will have to take care that your controls are properly resized to fit the title.
