In Poland, the most common layout is the `Polish (programmers)', virtually the same as US layout, with extra right Alt switching for polish accented characters. The alternative is `Polish (typewriter)' layout, with accented characters replacing most of punctuation, which doesn't seem to have caught on. Apparently entering accented characters with right Alt is comfy enough. Surprisingly all that happened in spite of MS Windows default settings -- IIRC up to and including Windows 98, MS Windows defaulted to the legacy `Polish (typewriter)' layout, and only since Win XP (or perhaps 7) it defaults to the common `Polish (programmers)'. At any rate, have a look at http://www.colemak.com/ http://www.colemak.com/ which is quite programmer-friendly. I am using a variation of it.
