this is what I came out, if you prefer to keep the laps on top a solution could be to rotate everythin 90 degrees (to still have enough space for the laps buttons.
is just a mockup but is something I could work on (I like to see where my results are going to be show ) In case you would give a try I use python+pygame (so I dont have to loose my mind with gtk interfaces and hildonizations) and since the games are always time critical I think pygame is the best solution for this kind of apps.
My clock sources are here: you can probably find everything you need to write the code by yourself. Being my 1st python app is very simple (and often not very python) so u can easily take the things you need (maybe just start with the very 1st versions to see how access the timer and manage a bit the numbers. Im sure is not the best code and you can probably find a lot of better way to do the things (Im not a programmer) but its a begin and show all the python tricks you probably need
