Is it what you're looking for ??
fiddle : http://jsfiddle.net/dUkz4/3/
html :
<div class="btn-group" data-toggle="buttons-checkbox">
    <button type="button" class="btn btn-primary">Sun</button>
    <button type="button" class="btn btn-primary">Mon</button>

UPDATE After comment:
You can customize the css for the space :
.btn-group .btn{
    margin-right:5px;
}

And make something like
<div class="btn-group row-fluid" data-toggle="buttons-checkbox">
        <button type="button" class="btn btn-primary span1">Sun</button>
        <button type="button" class="btn btn-primary span1">Mon</button>
        <button type="button" class="btn btn-primary span1">Tue</button>
        <button type="button" class="btn btn-primary span1">Wed</button>
        <button type="button" class="btn btn-primary span1">Thu</button>
        <button type="button" class="btn btn-primary span1">Fri</button>
        <button type="button" class="btn btn-primary span1">Sat</button>
    </div>
