I second the suggestion to use pstricks. It is easy create the boxes,
color them and put the text in them. And you can easily scale anything
to fit, as the OP pointed out.

I was able to draw a little calculator in pstricks in just a few
minutes,

[if you want to take a look at the result, see here: http://www.ptmat.fc.ul.pt/~lsequeir/calculator.pdf
]

so feel free to use this and customize to your heart's content.

I began by defining a command to draw and place any calculator button.
They can be of different sizes and colors, so the command expects this
info in its parameters.

%a command to draw and place a calculator button
%usage:
%\calcbutton{x}{y}{halfwidth}{halfheight}{color}{text}

\newcommand{\calcbutton}[6]{%
\rput(#1,#2){
\psframe*[linecolor=#5,framearc=0.4](-#3,-#4)(#3,#4)
\rput(0,0){\textbf{#6}}
}
}

Now we can draw our little calculator in a pspicture, such as the
following example (which yields the picture in the above link):

\begin{pspicture}(0,-1)(6,10)
\psframe*[linecolor=yellow,framearc=0.2](-1,-2)(9,10)
\psframe*[linecolor=cyan](0,7)(8,9)
\multido{\n=1+1,\i=1+2}{3}{\calcbutton{\i}{1}{0.85}{0.5}{lightgray}{\n}}
\multido{\n=4+1,\i=1+2}{3}{\calcbutton{\i}{2.5}{0.85}{0.5}{lightgray}
{\n}}
\multido{\n=7+1,\i=1+2}{3}{\calcbutton{\i}{4}{0.85}{0.5}{lightgray}{\n}}
\calcbutton{2}{-0.5}{1.85}{0.5}{lightgray}{0}
\calcbutton{5}{-0.5}{0.85}{0.5}{lightgray}{.}
\calcbutton{1}{5.5}{0.85}{0.5}{red}{C}
\calcbutton{3}{5.5}{0.85}{0.5}{lightgray}{$\pm$}
\calcbutton{5}{5.5}{0.85}{0.5}{lightgray}{$\div$}
\calcbutton{7}{5.5}{0.85}{0.5}{lightgray}{$\times$}
\calcbutton{7}{4}{0.85}{0.5}{lightgray}{$-$}
\calcbutton{7}{2.5}{0.85}{0.5}{lightgray}{$+$}
\calcbutton{7}{0.25}{0.85}{1.25}{green}{$=$}
\end{pspicture}

Notes:

1) As always, when using pstricks, you must use "TeX & Ghostscript"

2) Also, don't forget to

\usepackage{pstricks,multido}

(I used multido in this example, but you can do without it and draw
each button individually)

3) Feel free to email me privately if you need further assistance. I
am on digest mode, and also possibly some details may not be of
interest to most members.

4) As to the size of the text: you can \scalebox or \psscalebox or
\psscaleboxto as needed; and, if necessary, make use of pstricks'
clipping facilities.
