You could fly into Geneva (Switz) - head down to Chamonix (FRA) - go through the Mt Blanc Tunnel into Italy.
I would suggest going to Lake Como - if you are interested Zermatt (Switz) is pretty awesome.
From Como - you can go to Verona, Siena, Florence, Roma - that would be a great two week trip.
Here's the google map of the route https://www.google.co.nz/maps/dir/Geneva...
If I were you I would choose Germany or France because here you have many beautiful places to visit .. For example Paris or C?te d'Azur if you want to swim :) . Germany is very interesting and wonderful ,is one of my favorite. you can visit the big cities like Munchen ,Frankfurt or if you want something historic you must go in Heidelberg ..Germany is very peaceful and clean and you can feel confortable here.
I hope I helped you :)
i can suggest you a interesting tour ... start Lyon (france) or Turin (italy) you can visit Turin and proximity in a week (in turin you can see: Royal Palace, Madama Palace, Venaria hunting palace, Carignano palace with first italian parlment, egyptian musem, car museum, cinema museum, rivoli castle, exilles fortress, fenestrelle fortress, sacred of st Michael, medieval village and the park) (near turin you can see: ricetto di candelo and menabrea brewery, one of the best beer all around the world, lago maggiore and isola madre... you should spend at last a day here) then you could go in aosta valley... here you can see a lot of wonderful castles/fortresses... then you can cross the mt blanc tunnel and go in france... here you could spend a week visiting chambery avignon lyon annecy (a wonderful village i loved it) and crossing the border again geneve
You land in Rome, fly to (or take the train to) Verona, then a short stop to Venice and back to verona, then train to Innsbruck and train again to Germany Rosenheim and Prein, then Munich and back home.
I suggest you go to the travel section of your local library and read up about those countries and others and see what you might enjoy.
