I want to create pie menu with possibility to make,edit,delete and choose quick selection sets.
For example on components selection i want quick set selection set with pie menu.
Now when i use “bpy.ops.object.vertex_group_add()” is only create a group but without selected components.
You need to use bpy.ops.object.vertex_group_assign() operator to add the selection to the new vertex group:
bpy.ops.object.vertex_group_add(); bpy.ops.object.vertex_group_assign()
Not sure how you want to use this menu and how it should look. Can you post some pic?

It is possible to with pie menu open floating Vertex Groups window?
Try this code in Custom tab:
panel('DATA_PT_vertex_groups', area='PROPERTIES')
