You can use a non-modal form

an example with IronPython
test Wpf no modal form

import clr	
import sys
import System
sys.path.append(r'C:\Program Files (x86)\IronPython 2.7\Lib')
sys.path.append(r'C:\Program Files (x86)\IronPython 2.7\DLLs')

#import Revit API
clr.AddReference('RevitAPI')
import Autodesk
from Autodesk.Revit.DB import *
import Autodesk.Revit.DB as DB

#import net library
from System.Collections.Generic import List

#import transactionManager and DocumentManager (RevitServices is specific to Dynamo)
clr.AddReference('RevitServices')
import RevitServices
from RevitServices.Persistence import DocumentManager
from RevitServices.Transactions import TransactionManager

doc = DocumentManager.Instance.CurrentDBDocument
uiapp = DocumentManager.Instance.CurrentUIApplication
uidoc = uiapp.ActiveUIDocument
app = uiapp.Application
sdkNumber = int(app.VersionNumber)
