The above error message and the following:

    $ fgrep 126 /usr/include/w32api/winerror.h
    #define ERROR_MOD_NOT_FOUND 126L
    ...

imply that plpython.dll is failing to load.  I believe that this is
because a dependent DLL can not be found:

    $ cygcheck plpython.dll
    Found: .\plpython.dll
    .\plpython.dll
      C:\cygwin\bin\postgres.exe
        C:\cygwin\bin\cygwin1.dll
          C:\WINNT\System32\KERNEL32.dll
            C:\WINNT\System32\ntdll.dll
*>    C:\cygwin\bin\libpython2.2.dll
*>      C:\cygwin\bin\cygcrypto.dll
*>      C:\cygwin\bin\cygssl.dll

Do you have the above marked DLLs on you system?  Does python work
properly from bash?

BTW, the following seem to work OK for me:

    $ psql
    Welcome to psql 7.3b3, the PostgreSQL interactive terminal.
    ...
    jt=# CREATE FUNCTION plpgsql_call_handler () RETURNS OPAQUE AS '/lib/postgresql/plpgsql.dll' LANGUAGE 'C';
    CREATE FUNCTION
    jt=# CREATE FUNCTION plpython_call_handler () RETURNS OPAQUE AS '/lib/postgresql/plpython.dll' LANGUAGE 'C';
    CREATE FUNCTION
