Yes an MDI interface is probably what you are looking for.
And I can understand the dilemma you are facing with an application that has several different areas of action but you don't know if the user wants to do
this, that or the other so you have this blank looking form there waiting on the user to select a section to go into.
You can do a couple of things to alleviate this boring looking form.
You can go into one of the modules/areas by default and when the user exits your program you can bring up the last module/area they were in. This is also helpful if you only allow one instance of your program but if you allow multiple instances or a limit of multiple instances you will have to add logic for keeping track of which instance is in which area.
You can add a graphic (I see a graphic that says which computer do you want to sink today

). While not the best way to make it look professional you can search the web for creating an instance of a screen saver (search
and other code sites) or some other animation.
I also see the button idea, but that is also a little plain don't you think? You could always add other status information (use your imagination). But still, a little plain looking.
Good Luck in whatever direction you go and don't forget to read FAQ222-2244.
