I have been looking through a lot of questions and their relative answers to solve this, but could not quite find the help I need. I want to create a Beamer template for my frames and my title frame, eventually derivated from the Goettingen theme (p. 150, CTAN documentation).
I tried creating my own .sty files, defining and redefining the commands, working with the head- and footlines, etc. but could not manage to get exactly what I want, and I'm getting lost in all the possibilities. The closest MWE I got so far is the following :
\documentclass[french]{beamer}

\begin{theorem}
There is no largest prime number. \end{theorem}
\begin{enumerate}
\item<1-| alert@1> Suppose $p$ were the largest prime number.
\item<2-> Let $q$ be the product of the first $p$ numbers.
\item<3-> Then $q+1$ is not divisible by any of them.
\item<1-> But $q + 1$ is greater than $1$, thus divisible by some prime
number not in the first $p$ numbers.
\end{enumerate}

So far, it gives me these frames :
But I'm looking for something like this (.ppt made) :
So, for now, I could not manage to get the headline to accept the logo and the supervisors' names vertically centered, and I would love to be able to customize the foot- and headline like I did in a report document, i.e. with :
\lhead{\insertlogo}
\chead{\bfseries Title}
\rhead{ \textsl{Report}}
\lfoot{YXX}
\cfoot{\bfseries \textsl {\small \textcolor{Red1}{\fbox{IMPORTANT THING HERE}}}}
\rfoot{\thepage}
Thank you for any help you could provide, it is much appreciated.
