Putty connection manager download for windows 7

PuTTY Connection ManagerI have just stumbled upon PuTTY Connection Manager, an application which allows having multiple tabs, i. e. simultaneous PuTTY sessions open at the same time.
I am wondering whether this useful piece of application can be provided within a portable application?
I see one problem: PuTTY Connection Manager needs Microsoft's .NET Framework installed on the computer. Maybe a portable installation routine could check whether the framework is installed and, if so, display a question whether it should be installed or not. Just an idea.
If it's not possible, here's the link for you PuTTYers:
