Me neither - but IIRC using gettext (dxgettext) was something /incredibly/ easy :
the translating function is called '_()' :) (yes, function _([const] input: string): string; )

 (allegedly, in newer (dx)gettext, not even that- it's enough to have (dx)gettext unit included, 
  but don't quote me on this one).

Then the dxgettext handling program creates the strings to be translated list out of that 
(saves to text .po file), together with programmatic context they are used in, 
as a help for the translator - and then compiles to .mo (pls sbdy correct me if I'm wrong) 
which are loaded at program start/on demand/as resourcestrings, (and IIRC may already support 
UTF-8/Unicode/multiple bytes per character strings too - do you)?

The gettext program is out there for (almost) all platforms, AND there are plethora of translation-handling
programs compatible with it, out there too, but you could well enough handle it by editing
the po files in any decent text editor.

So you don't want to translate it all at the same time, is that what it is?
Only the strictly necessary portions/snippets as you call them?

Please forgive my attitude - but it looks like a very-low level and hence very
inflexible and very un-Pascal solution to this problem. I think, this is what 
people were trying to suggest to you.
