the win32 api to read the event log is :

BOOL ReadEventLog(

  HANDLE hEventLog,                // handle to event log

  DWORD dwReadFlags,               // how to read log

  DWORD dwRecordOffset,            // initial record offset

  LPVOID lpBuffer,                 // buffer for read data

  DWORD nNumberOfBytesToRead,      // bytes to read

  DWORD *pnBytesRead,              // number of bytes read

  DWORD *pnMinNumberOfBytesNeeded  // bytes required

);

i guess you could use Win32::API to call this API and read the event logs...
