1. Make sure the button has BS_BITMAP style
2. Load the bitmap with
SendMessage( m_hWnd, BM_SETIMAGE, (WPARAM)IMAGE_BITMAP, (LPARAM)hBitmap ),

Use LoadBitmap to load the bitmap from resources, e.g.
HBITMAP hBitmap = LoadBitmap( IDB_BITMAP1 ) ;

3. If you simply want to paint the button, override OnDraw, then you can use FillSolidRect to paint the button with your chosen color.
