You need Cygwin to be able to run the treetagger scripts on Windows. The error message
CreateProcess error=193, %1 no es una aplicación Win32 válida
suggests to me that you have not set the shell.path
system property to point to your Cygwin sh.exe
, as explained in the TaggerFramework section of the user guide.
For OpenNLP there are some name finder models available at http://opennlp.sourceforge.net/models-1.5/ and POS tagger models at https://github.com/utcompling/OpenNLP-Models/tree/master/models/es but I can't see tokeniser or chunker models anywhere. For tokenisation and sentence splitting I suspect that the default GATE Unicode Tokeniser (not the "ANNIE English tokeniser") and either of the default sentence splitters will do a reasonable job.
It might be worth subscribing to the gate-users mailing list and asking on there whether anyone else has any Spanish resources they would be willing to share.
