ONE script required - windows desktop qt app with plugin for scripting .net java-script python

I need a windows desktop qt app that will have three plugins: 1. will edit(with syntax highlighter), run and debug qt java-script based scripts with access to the main application. (your choice of direct object access with wrapper or ActiveX access) 2. will edit(with syntax highlighter), run and debug python scripts with access to the main application objects (your choice of direct object access with wrapper or ActiveX access) 3. will edit(with syntax highlighter), run and debug .net scripts with access to the main application objects (your choice of direct object access with wrapper or ActiveX access) If you chose to use ActiveX, main application will provide access to the objects over ActiveX. Project will be broken in three sections, one for each language. You are free to start with the .net or java-script one. The Java-Script has extensive support in QT. That is expected to be a quick implementation. Please note that what I want is one of the scripts, not all three. The other two will be additional as different stages of this project.
