Hi ,
Can any one help me with bitmap creation . I need to create header for bitmap and add palette information (not 24 bit bitmap) in plane C++ so it can be used both in Linux and windows.

This is a well known format. These links should help:
http://en.wikipedia.org/wiki/BMP_file_format

Check out BITMAPINFOHEADER

Is there any particular problem you are having.  I'd say since Microsoft is still unfortunately more popular that other OSs have to read any BMP format that produce so I might just do it their way.

Here are their structures related to bitmaps:
http://msdn.microsoft.com/en-us/library/windows/desktop/dd183392%28v=vs.85%29.aspx

BITMAP
BITMAPCOREHEADER
BITMAPCOREINFO
BITMAPFILEHEADER
BITMAPINFO
BITMAPINFOHEADER
BITMAPV4HEADER
BITMAPV5HEADER
BLENDFUNCTION
COLORADJUSTMENT
DIBSECTION
GRADIENT_RECT
GRADIENT_TRIANGLE
RGBQUAD (OF COURSE THAT IS A, R, G, B (TRANSPARENCY(ALPHA), RED, GREEN, BLUE)
RGBTRIPLE
SIZE
TRIVERTEX

I have read a bitmap before using these structures, but never needed to make one. I'd think you just fill them out with the correct info, and one structure uses one or more of the others.  there are probably a lot of RGBQUAD instances for example. I seem to also remember something about things being upside down and having to interpret -numbers in a special way.
