I'm not sure I understand your question, but here are some resources
for translating a PyQGIS plugin:

http://qt-project.org/doc/qt-4.8/linguist-manual.html

http://qt-project.org/doc/qt-4.8/qobject.html#tr

http://www.riverbankcomputing.co.uk/static/Docs/PyQt4/html/i18n.html

Basically, you need to wrap all visible, translatable strings with a
given QObject's tr() or trUtf8() method, or
QtGui.QApplication.translate(). Then, pylupdate4 can be used to
generate the .ts files for use in Qt Linguist.

When working in Qt Creator or Designer, make sure any gui item's text
you want translated has 'translatable' checked (default). Then, it's
pyuic4-generated .py will have wrapped strings.

Most PyQGIS deployed plugins have their .pro file removed, but the
'Shift Points' and 'EasyPrint' plugins have a .pro, MAKEFILE and i18n
directory setup in their source you can examine. Both also show how to
instantiate the QTranslator() object in their base classes, for
effecting the plugin's on-the-fly translation.
