Button bar - how would you create this?

Hi guys,

I'm just started learning Titanium and stumbled into at problem. I want to create a Button bar. I can't use the build in Titanium.UI.ButtonBar since I need to change the fontSize and fontFamily properties. I can't do 3 individual buttons since I only need rounded corners on the left side of the left button and the right side of the right button.

My question is, how would you resolve this problem? At the moment I'm thinking of creating the button bar in html/css and create a webview for it, but I think this solution is quite tedious?

Here is a picture what I want to create: http://titeo.dk/clients/temp/buttonBar.jpg
