Here's some (untested) example code that should work:
// assuming that your icon resource is in the programs .exe

 HPOINTER  hptr;        // Pointer handle.
 HWND      hwndDlg;     // Dialog window handle

 hptr = WinLoadPointer(HWND_DESKTOP, (HMODULE)0, ID_ICON1);
 WinSendDlgItemMsg(hwndDlg, ID_ICON, WM_SETICON, MPFROMLONG(hptr), 0);

// A possible resource definition of the dialog could be for example:

ICON   ID_ICON  icon.ico
ICON   ID_ICON1 icon1.ico

DLGTEMPLATE 256 850 MOVEABLE DISCARDABLE
BEGIN
    DIALOG "Dialog Title", 256, 123, 101, 200, 91, FS_NOBYTEALIGN |
                FS_DLGBORDER | WS_CLIPSIBLINGS | WS_SAVEBITS | WS_VISIBLE,
                FCF_TITLEBAR | FCF_SYSMENU
    BEGIN
        CONTROL ID_ICON,               ID_ICON, 87, 56, 21, 16, WC_STATIC,
                                            SS_ICON | WS_GROUP | WS_VISIBLE
    END
END

Hope this helps..
