[pygtk] licenses

[Martin Bílek]

hi all,
i know that is many software licenses.
coz my english is not good i dont know how to use.

Question is:
May i sell application (written using python,
pygtk and pygtksourceview2) to my employer or somebody without source
code. just executable (using cx_freeze) or in compiled bytecode ?

with python and pygtk no prob i think [ WingIDE ]
but with PyGtkSourceView2 which is LGPL i think.

thanks for answers.
