Khubaib,
I don't know how to programaticly add or remove the keyboard layout, but You may create an INF file & run instalation from it:

TEXT TO lcINFFile NOSHOW

[version]

ENDTEXT

STRTOFILE(lcINFFile, "InstKeyb.INF")

DECLARE INTEGER ShellExecute IN Shell32.DLL INTEGER hwnd,;
                                         STRING lpOperation,;
                                         STRING lpFile,; 
                                         STRING lpParameters,;
                                         STRING lpDirectory,;
                                         INTEGER nShowCmd
                                         
ShellExecute(0,"install","InstKeyb.INF","","",1)

This will install kbdBF.dll as a Keyboard LayOut named Bulgarian (Phonetic) in Windows\System32 dir. That INF file is prepared for Windwos XP SetUp.
The DLL must ne in the same folder as newly created InstKeyb.Inf
