[Tex/LaTex] rectangles in beamer background canvas

backgroundsbeamer

I am trying to create a custom title page in Beamer, and I've tried many things, but I'm just helpless with all the solutions I found.

I would like to create only in the title page, the following structure:

A wide rectangle on top (from side to side) with blue color (width=slidewidth, hight 3 cm), then should come my presentation text and other info, and in the bottom I wan to put the same rectangle … (width=slidewidth, hight 3 cm).

I would like the rectangle to be part of the canvas, so I could insert the institute logo overlaid above the bottom rectangle. Any help would be appreciated.

UPDATE:

I managed to insert the fancy rectangels, but they are inside the text space, and I can't put them yet inside the footer and headers …

here is what I did:

 \setbeamertemplate{title page}
   {
   \begin{beamercolorbox}[ht=2cm,wd=\paperwidth]{title in head/foot}
   \usebeamerfont{title in head/foot}
% {\centering \hskip3.5cm \includegraphics[scale=0.15]{FZD_LOGO.png}}
% \vskip1.25cm
\end{beamercolorbox}%

  \centering{
    {
    \usebeamerfont{title}\usebeamercolor[fg]{title}
    \inserttitle
    } 
    }
%     \vskip5cm
\vskip1.cm
\begin{beamercolorbox}[ht=2cm,wd=\paperwidth]{title in head/foot}
\usebeamerfont{title in head/foot}
{\centering \hskip3.5cm \includegraphics[scale=0.15]{FZD_LOGO.png}}
\end{beamercolorbox}%
% \end{minipage}
}

Hi some thing like this could help: 

\documentclass{beamer} 

\title{Stackxchng} 
\author{McCool} 
\institute{sth}
\date{the day the music died}   



\begin{document} 

\setbeamercolor{my thing}{fg=red, bg=black}% you can use every beamer color 
 \setbeamertemplate{title page}
   { 
\begin{beamercolorbox}[ht=2cm,wd=\paperwidth, left, sep=.5cm]{my thing}
 \color{black}Upper % use every color you want
\end{beamercolorbox}%
\vskip0pt plus 1filll % see beamerusersguide

\begin{centering} % some Text Macros
 \inserttitle 

  \insertsubtitle 

 \insertauthor 

 \insertdate 

  \insertinstitute 

   \inserttitlegraphic
\end{centering}
\vskip0pt plus 1filll % again tantau magical
\leavevmode \begin{beamercolorbox}[ wd=\paperwidth, ht=2cm, sep=.5cm]{my thing}
  \color{black} Lower % or what ever you like
\end{beamercolorbox}%
}



\frame[plain]{\titlepage} % PLAIN!
\frame{just a frame}
\end{document}

Hope that helps
