Drag-Drop, draw on Maya's viewport

[illunara]

Hi everybody
This is one part in our project, our goal is create a tool which allow user can draw some path on viewport (If possible)then use it to select element (Faces, vertex, edge....).

So like the title said, what i want to ask is, can i change some Maya's behavior (like drag-drop on viewport) or tool (like lasso select tool) to make it happend?

If not, then i can i create a new UI (use PyQt or PySide) which contain Maya's viewport?

Thanks
