I would like to create plugin based on framework - http://wpmvc.org. Will my plugin be accepted in wordpress plugin directory ?
Welcome to wordpress.stackexchange.com.
I don't think plugins with frameworks are allowed, sorry.
Here are Detailed Plugin Guidelines
And here about Writing a Plugin

Yes, you can use a framework to build your plugin.
What you can't do, is submit a plugin that's just the framework itself (so that others can require your plugin as a dependency, for example).
Using a framework will neither get your plugin automatically approved nor rejected. It will depend though, on your adherence to the Plugin Guidelines.
